Welcome to Gaia! ::

Yes.
Any "You take another turn" spell (which all I can remember are Time Walk, Time Warp, Beacon of Tomorrows and now Walk The Aeons from Time Spiral) + Panoptic Mirror = Infinite turns if you want. Remember the mirror is a "you may"

gonk Sorry for missing that.

The answer is no. When the +1/+1 counter goes he's a 0/0 and dies from state based effects. You won't have time to regenerate him. Another possible scenerio for this is when he dies from combat damage and you attempt to modular onto another creature. Modular only triggers when the creature is put into a graveyard. Regenerating does not bring it back from the dead it only prevents the death from happening. So you could regenerate him. But nothing gets a +1/+1 counter.

Well no. You can use shuriken more than once. If you have some ninjas. Example
You have one ninja of the deep hours and one other creature. You equip the shruiken. Use it from the ninja. Attatch it to another creature, then use that one. Now your opponent has control of it before you can equip and use it again (unless you had help from a Certain Leonin )
All creatures have summoning sickness. Period. Artifact or not. (unless they have haste)
All non creature premanents do NOT have summoning sickness.

That rule only applies to multiplayer and no. By most multiplayer rules that end effect of Arcande Denial is attatched to the player still in the game. Example
Player A denial's player Bs spell.
Player C kills player A
Next turn of Player B. Player B draws a card during his upkeep.

(NOTE: You MIGHT have to double check me. I'm not up to par on multiplayer rules anymore and I COULD be wrong about that.)

1 on 1 the player who goes first does not draw a card during his/her first turn draw step.
In multiplayer its a common rule that everyone draws on turn 1 going first or not (least that's how I've seen things.) so for 1 on 1 whoever goes first doesn't draw on the first draw step.
Second: Mana abilities don't use the stack. You can play them whenever you want any time you want and they can't be responded to.
NOTE: This does not mean you can tap your Llanowar Elves for G on the first turn they come into play. They still need to get off summoning sickness and then you can use them as you see fit whenever you see fit.

This is my specialty area, one could say. I play a lot of multiplayer Magic. Several friends have "fun" decks, mostly that involve simultaneously killing off everything and / or everyone. Quite fun.

Anyways, you're quite right in your assumption. In the case of Arcane Denial and any other cards that "tag" effects on to players, OR other permanents in play, the effect stays "on the stack," so to speak. That is, it will still happen.

The only case where a "tag" effect would NOT have an effect, is if the player / permanent that it would effect is killed / destroyed. Arcane Denial cannot, for example, carry out its tag on a dead player.

Otherwise, you could spam Arcane Denials on an opponent as a dying gift, if you were to lose, for example.

Any other mutliplayer questions, or questions in general, feel free to ask.

No. They don't double up from what I understand. Each doubling season is a replacement effect of the same thing. So having two of them is redundant. You'd only get 2. Though, let's say some time later in the day I find a real answer to this because I'm not too sure, it could be it places 4 into play. (start with 1 double it to 2 then double that to 4) I'll edit this post with a referrence link if I can find an answer to what double Doubling Seasons do.


EDIT: Star City Games 'Ask The Judge'



Double Edit: So yes. I was wrong. You would get 4 Saprolings not 2 from having 2 doubling seasons.

I know this is a stupid question, but do "Stormed" and "Replicated" spells count toward a storm count? I highly doubt it, but I just had to throw it out there.
