Gogo, Master of Mimicry + Vhal, Candlekeep Researcher + North Pole Patrol

Gogo, Master of Mimicry

Vhal, Candlekeep Researcher

North Pole Patrol

How it works

1. Activate North Pole Patrol by tapping it, targeting Gogo.
2. Holding priority, activate Vhal by tapping it, adding at least CCCCC that cannot be spent to cast spells from your hand.
3. Activate Gogo by paying 4 and tapping it, copying the North Pole Patrol ability, targeting Gogo and Vhal.
4. Resolve both copies of the North Pole Patrol abilities, untapping Gogo and Vhal.
5. Repeat from step 2.

This clever loop turns Gogo, Master of Mimicry into a relentless untap engine by leveraging its ability-copying prowess on North Pole Patrol. While North Pole Patrol's basic tap normally untaps just one permanent, Gogo multiplies that trigger to refresh both itself and Vhal, Candlekeep Researcher simultaneously. Vhal then provides the heavy lifting by tapping to generate an abundance of restricted colorless mana, paying the {4} activation cost for Gogo's copying while leaving you with infinite colorless energy for whatever non-hand spells or abilities you desire.
