Only Blood Ends Your Nightmares This scheme would be so much better if it said nontoken creature. Only Blood Ends Your Nightmares is nice when you force them to discard two cards from their hand or a sizable creature, and its also good that every opponent loses something
For X and one Blue or Black, you choose a color, then an opponent exiles X cards from the top of their library
In theory, you could cast off an entire hand of spells, discard a hand of zero cards, and still restock your hand at your end step
1-mana removal, even with a downside, can be a powerful tempo play, and you can target your own creatures, in particular your indestructible creatures, to get some upside
