mtg cards that make opponents spells cost more Kasmina, Enigmatic Mentor | War of the Spark | Modern Ertai's Scorn

These are very similar to the old Magic: The Gathering prerelease promo cards that we recently discontinued, much to the frustration of Magic players

Each The Lost Caverns of Ixalan Set Booster Box contains 30 The Lost Caverns of Ixalan Set Booster Packs

If an effect causes The Aetherspark to become attached to a creature while it is being attacked, it will continue to be attacked

Each booster pack has 12 cards each, which starts budding Illumineers off with 48 cards

However, if there are easy repeatable methods of gaining life (even Ajanis Mantra, given that there will presumably be more lifegain/drain payoffs), then Epicure of Blood could be a surprisingly decent win condition in a grindy deck, or a way to get in those last few points of damage
