Oh yeah. Everything you've always dreamed of right here.
These will play as written on the card and as originally intended.
"Any Instant/Sorcery/Creature/Land card outside the game or in exile"
When these were originally printed, you could grab cards in the exile zone simply because it wasn't considered a zone in the game at the time.
And yeah, you're reading that right, any card you can sleeve up and put in your deck at that moment. And of course you can break singleton! This is Vintage cube ain't it? Go for broke!
This does seem a little broken, but I'd like to test it to find out. It at least seems fun, and I'll likely get to see cards get played that would otherwise not see the light of day in cube. I've also tested Contract From Below and really these cards can't be any worse than trying to make that card fair.
I'll do a write up on my plans for the Wishes later, but if you're curious now, They are going to be played as on the card and intended.
You can grab any card you own outside the game OR in exile. Borrow a card from a friend or buy a card off the shop. Semantics aside, the intention is: if you can sleeve up a card in that moment, put it in your hand.
I'm ready to see what shenanigans come up. It's gonna get silly for sure.
It's also a good way to test cards that probably would never see the light of day in cube.
I understand Runaway Steam-Kin is one of the best mono red cards, but Kari Zev is just fine as a replacement, and it gives a little extra fodder for incentive to play black/red.
