Underrated?
Crashing Footfalls, Living End and Glimpse of Tomorrow are all stopped with a 0-mana Chalice of the Void other use cases for the card are for example disabling Lotus Bloom out of the Tameshi Bloom deck or preventing Affinity decks from playing their Ornithopter, Memnite, Welding Jar and co
The most important, however, is certainly Greymond, Avacyn's Stalwart - the rebranded version of Rick Grimes
(You cant be the target of spells or abilities your opponents control.) Prevent all noncombat damage that would be dealt to other creatures you control
Theres also the utility in having access to Lukka in a reanimator build, but I havent been in a position where its been relevant yet
I think this deck is hard to get working and still seems pretty underpowered, but Ich-Tekik is green so you can play a lot of ramp and Colossuses and see what happens
