Off the bat, Drag Race lends itself well to spell or item cards, similar to Yu-Gi-Oh!s equip spells or Magic: The Gatherings artifacts
Keep in mind though that you can only add two of each card in a deck and cards can be reused in multiple decks, so there's no need to hoard your duplicate cards
Personal preference ultimately depends on favorite characters and collecting goals
The -3 lets you destroy a target creature, and finally, the -6 gives you an emblem that states "whenever you gain life, target opponent loses that much life." Given that this card only costs four mana to cas t, it, like most of Witherbloom, is quite finely balanced and should see plenty of play across Standard and Commander
That's fine, I guess
Obviously, you cant enchant creatures with shroud, though , because those cant be the target of any spells or abilities, including your own
