The "cast until end of turn" thing is a lot less red when you choose what cards to put into it and then choose when to activate it.

Mythic?

@Jackal: Maybe "At your end step, exile a card. If you draw a card. Then, if exiled 5..."

Other than red card advantage what is the most fun thing about this card? I am also not a fan of transforming and sacrificing in the same turn. It all feels like it wants to be a single ability except that it is too complicated to fit on a card.

It doesn't want to be a single ability because it has a lot of flavor to it, too.

I think this is fun for lots of the psychographics. It promises 'one big turn'. It gives red some powerful and interesting card advantage. And it's interesting strategically in what you decide to put in.

Jackal, I'll freely admit that the backside isn't very red. That is my mistake. It's not a break, I think, but it's definitely a sizable bleed. This was originally blue, but the frontside is so red...

I really like the front side, but the backside definitely needs work. I'll take suggestions.

Agree with Jackal about it not quite justifying DFC:

­, Exile a card from your hand: Draw a card. As long as five or more cards are exiled by ~, you may play them. At the beginning of the end step, if you played any cards exiled by ~, sacrifice it.

I think my problem is that the exile can't feel like "save for later" Timmy would be happy if the back side is a big red enchantment like furnace of rath or "Creatures must attack and get haste and doublestrike when they ETB" and other psychographics enjoy making sure they have the right hand/board when it comes online. If you like referencing the exiled cards it could be something like "Discard a card that shares a name with an exiled card: deal 3 damage to something"

Nice idea, Jay. I think that works.
