Q:During the Declare Blockers step, if you declare blockers (or no blockers) and your opponent plays an instant or flash creature, can you change your blockers?
Short answer: No, you can’t.
Longer answer: Combat is broken up into several different steps, and players have the opportunity to play spells or use other effects in between each step. Once you’ve moved to a new step, it’s too late to go back in time and change your decisions from previous steps.

Q:Hello, I was wanting to get your opinion on something (and maybe some of your other followers' opinions too). I am going to a casual FNM at a local store this week and I haven't played since Return to Ravnica. They said that it doesn't matter how old my cards are, and I have a couple decks built from back then. But I am just wondering if it would be better use those or to try to put together a deck that is more up to date? Thanks!
This is really a question for whoever runs your shop, depending on what format (if any) the FNM is adhering to. If it’s a Standard (Type 2) event, then only cards from Theros, Born of the Gods, Journey Into Nyx, Magic 2015 and Khans of Tarkir will be legal.
If we’re talking about a truly casual event with no set format, then whatever you want to play with goes. Newer cards are not collectively better or worse than cards from a few years ago, they’re just different and the sets are based around different themes and mechanics. I’d recommend taking a look at Khans and Theros blocks to see what they’re about and whether you like what’s in them. (I personally really enjoyed both of them, and I think you will too.)
Q:If i use Delve to pay for Empty the pits, does the card i exile cover two X's or only one? Thanks :)
Each card you exile replaces paying 1 mana.
In other words, every two cards you exile (and/or every 2 mana you pay) gets you one extra Zombie.
For example: If you decide to cast Empty the Pits for X = 2, the total cost of the spell is 4BBBB (eight mana). Legal ways to pay that cost include:
- Pay BBBB, and exile four cards from your graveyard.
- Pay 1BBBB, and exile three cards from your graveyard.
- Pay 2BBBB, and exile two cards from your graveyard.
- Pay 3BBBB, and exile one card from your graveyard.
- Pay 4BBBB (and exile nothing).
Q:If I make a copy of an opponent's morph creature (for example using clever impersonator), can I morph it face up, or is it just a nameless 2/2? If I can turn it face up, is my opponent required to show me what it is when I copy it so I know its morph cost?
Based on oracle ruling, I am not sure if this is infinite tokens or not… Based on the way things are worded, it looks like they don’t stack together because they are differently named permanents. But I really don’t think it was intended to make infinite between the 2… Anyone know what the rules actually say about this?
"If there are two Doubling Seasons on the battlefield, then the number of tokens or counters is four times the original number. If there are three on the battlefield, then the number of tokens or counters is eight times the original number, and so on."
"If you control two Parallel Lives, then the number of tokens created is four times the original number. If you control three, then the number of tokens created is eight times the original number, and so on."
It’s not infinite. Each replacement effect applies to an event a maximum of one time.
If you control one Doubling Season and one Parallel Lives, an effect which normally creates one token will create four tokens instead (each effect will double it one time).

Q:So yet again legacy decks have brought up a weird scenario that I need clarification on. In Mud list I'm looking into, they play play sets of Chalice of the Void and Trinisphere. If Chalice is set to a value less than three, and Trinisphere makes all spells less than three mana cost three mana to cast, does that mean that the spells that normally would be countered by Chalice aren't countered? Basically, can I have Trinisphere and Chalice out at the same time and they still work in my favor?
No, there’s no real interaction between these cards.
Chalice of the Void cares about the converted mana cost of the card, which is a fixed value a card has.
Trinisphere affects how much you have to spend to cast spells. This is an additional cost, and it follows the normal rules for additional costs.
Effects that increase or decrease the cost of spells (such as Trinisphere, or Arcane Melee) don’t have any effect on the spells’ converted mana cost.
For example, a spell with a printed mana cost of 1U has a converted mana cost of 2, even if Trinisphere means you have to spend 3 to actually cast it.
Note you won’t be able to do this with flying creatures.
This is a good point. Circle of Flame only triggers at the moment when a creature without flying is declared as an attacker. Casting Turn to Frog on a creature with flying to make it lose flying after it’s already been declared attacking won’t cause Circle of Flame to trigger.
You need the creature to lose flying before it’s declared as an attacker in order to trigger Circle of Flame.
The six keyword mechanics in the upcoming large fall set.
Q:Is it possible to to use Turn to Frog / Polymorphist's Jest to kill creatures with Circle of Flame? I'm a little unsure about the minutiae of the declare attacker step and when I get priority, and whether or not damage gets carried over once Turn to Frog resolves.
Yes, you can kill attacking creatures this way. It doesn’t matter whether you Turn to Frog the creature before or after it’s been dealt the damage from Circle of Flame, since the damage dealt by Circle of Flame remains on the creature until end of turn.
Note that if the creature is receiving any modifiers to its toughness — for example: if it has any +1/+1 counters on it, or if it’s enchanted by Hammerhand — then the 1 damage from Circle of Flame will not be enough to destroy it. Turn to Frog (and similar effects) only set the creature’s base power and toughness, and effects which add or subtract power or toughness are applied to the creature after that.
