Here's one fun combo: Necrobloom and Cultivator Colossus Necrobloom says lands in your graveyard have Dredge 2 (instead of drawing a card you can return a land in your graveyard to your hand and put the top 2 cards of your deck in the graveyard.)Cultivator Colossus says when it comes into play, put a land from your hand into play, then draw a card and repeat the process.So you put a land into play, and instead of drawing a card you Dredge 2. You put the land you pulled out of the graveyard into play and repeat the process until you run out of lands in your graveyard
