So, this essentially makes red's exile-but-can-be-played-this-turn into a second hand. Also, there are fringe scenarios like Apocalypse and Arc-Slogger, and looping of red cards with flashback, etc.. Unless I'm missing that "you control" must be a state in which the source is presently on the battlefield, like Abbot of Keral Keep being okay since it's a permanent and sticks while Act on Impulse wouldn't since it being a sorcery, goes away after resolution.

It's interesting, but I can't see the ability in hybrid, because the ability just doesn't feel like it could exist in mono-red. I mean, red takes risks for rewards, and this is just rewards, no risk.

It would be a golden UR card (no pun intended) to upgrade red's one-turn card draw into full card draw though. I agree with Sorrow that this shouldn't be done in mono-red

Takes a bit of thought to realise what this does - but yeah, I agree. It's a very nice card, and I could mayybe see it in mono-blue; but mono-red is a bit too bendy.

Should I mention this is a nightmare if you don't remember which of your opponent's cards have been exiled by non-red sources, and you think they might be cheating? Outside of that, I'm a fan.

Oh, other weird question. When you flashback a Firebolt, did you exile it by a red source you control?

Good points, folks. I edited it to no longer be hybrid.

The original intent is for it to allow things exiled by non-permanents to continue to be able to be played, but that could be changed if it's a power-level concern.

Oooh. What about Scorching Dragonfire and friends? The red spell sets up the death-replacement effect that exiles the card, so does this let me burn your creatures then cast them myself?

That was part of the intent. 😊

Oh I do like that. The 'obvious' use, of "Flashback, from exile, forever" is sadly going to be what people actually DO with it though. Which makes for boring repetitive decks. Not even "I turn red loot into really good loot" can compare with it.

Urk! Past in Flames. Win. (Surprisingly, the direct damage cards in red don't seem that effective when flashed repeatedly. Seize the Day is pretty scary though... as many extra attacks as you can afford)

I don't think Past in Flames works completely, unless the cards granted flashback are also red? I'm not sure on that, though.

Yeah, the spell with flashback exiles itself

I just remembered Kroxa, Titan of Death's Hunger. Nasty.

Oh yeah, escape is brutal with this. Delve too, but there's only one red card with delve
