How it works
Activate Emry by tapping it, targeting Jeweled Lotus.
Cast Jeweled Lotus from your graveyard by paying 0.
Displacer Kitten triggers, blinking Great Oak Guardian.
When Great Oak Guardian enters, it triggers, untapping all creatures you control and giving them +2/+2 until end of turn.
Activate Jeweled Lotus by tapping and sacrificing it.
Repeat.
This ingenious loop puts Emry, Lurker of the Loch in the spotlight, using her tap ability to continuously recast Jeweled Lotus straight from your graveyard for free. Every time you cast that artifact, Displacer Kitten's avoidance trigger blinks Great Oak Guardian, whose entry ability untaps Emry and your other creatures so you can tap Jeweled Lotus for commander-only mana and repeat the cycle. Because Great Oak Guardian untaps Emry and buffs your board, you generate infinite mana along with infinite creature and artifact triggers to overwhelm the table.
