Partner with Frodo, Adventurous Hobbit (When this creature enters, target player may put Frodo into their hand from their library, then shuffle.) At the beginning of combat on your turn, create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this token: You gain 3 life.") Activated abilities of Foods you control cost {1} less to activate.

Whenever a player casts their second spell each turn, you lose 1 life and create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

Permanents you control gain hexproof and indestructible until end of turn.

The Ring tempts you. Then reveal cards from the top of your library until you reveal X land cards, where X is the number of legendary creatures you control. Put those land cards onto the battlefield tapped and the rest on the bottom of your library in a random order.
