mtg modern horizons cards Echoes of Eternity (MH3-004) - 3 Another target creature you control gains protection from colorless or from the color of your choice until end of turn. MTG Modern Horizons 3 -

Id personally do Spirits for theme purposes, but I guess that since the creatures are getting the blessing, anyone can have it

Thallid Soothsayer + Thallid Omnivore Thallid Soothsayer and Thallid Omnivore are both fair sacrifice outlets for your Saprolings, but they fall short on flavor

Its a strong card to have around if opponents (or you yourself) are playing wheel effects, because it can profit from it by making some Bat tokens

You can play out vampires one by one and get an extra +1/+1 on board for each one you cast, or you could play token-makers like Charismatic Conqueror and Bloodline Keeper // Lord of Lineage to spread that vampire lord effect across more bodies with a single card from your hand
