Spider-Verse I could do without the cheesy spider text here, but eliminating the legend rule for spiders makes sense when you consider how many legendary spiders there are in Marvels Spider-Man alone

Call for Backup is a White/Red/Green +1/+1 Counters deck that showcases the brand new keyword "backup," enhancing your creatures with +1/+1 counters and abilities that last until end of turn

Hands to Keep I think it is important to view the deck in four components enablers (eight in total Entomb and Faithless Looting with eight creatures to discard), reanimation spells (twelve in total Reanimate, Animate Dead and Exhume), disruption (ten in total Thoughtseize, Unmask and Grief) and mana (twenty-two in total Lotus Petal, Dark Ritual and fourteen lands) The ideal hand in pre-board games is one that has a route to the combo (Entomb or Faithless Looting plus Creature, and a reanimation spell), a disruption spell (Thoughtseize, Unmask or Grief) and enough mana to make it all happen
