Sacrifice Sakura-Tribe Elder: Search your library for a basic land card, put that card onto the battlefield tapped, then shuffle
Suitable for 8 years and up, there are no new cards in here.
Underrealm Lich and Deadbridge Chant in particular do fantastic work here
While making a duplicate token might not do much in the grand scheme of things, giving them all +2/+2 can help push them over your opponents creatures
Theyll trigger on each end step, which means that sacrificing a Food on each of your opponents turns nets you an absurd amount of value
The card does a good impression of the Hunters From Hyperspace rule (which has gone through some variations), that would allow you to set them up outside the battlefield, only to bring them suddenly into play and destroy high priority targets
