Brinelin, the Moon Kraken + Gwenna, Eyes of Gaea + Primeval Protector + Earthquake Dragon

Brinelin, the Moon Kraken

Gwenna, Eyes of Gaea

Primeval Protector

Earthquake Dragon

How it works

1. Activate Gwenna by tapping it, adding that can only be spent to cast creature spells or to activate abilities of creatures.
2. Cast Earthquake Dragon by paying at most 1.
3. Brinelin and Gwenna trigger.
4. Resolve the Brinelin trigger, returning Primeval Protector from the battlefield to your hand.
5. Resolve the Gwenna trigger, putting a +1/+1 counter on it and untapping it.
6. Activate Gwenna by tapping it, adding that can only be spent to cast creature spells or to activate abilities of creatures.
7. Cast Primeval Protector by paying at most 1.
8. Brinelin and Gwenna trigger.
9. Resolve the Brinelin trigger, returning Earthquake Dragon from the battlefield to your hand.
10. Resolve the Gwenna trigger, putting a +1/+1 counter on it and untapping it.
11. When Primeval Protector enters, it triggers, putting a +1/+1 counter on each other creature you control.
12. Repeat.

This loop thrives on an infinite loop of massive, self-discounting threats fueled by Gwenna, Eyes of Gaea, whose mana production and continuous untaps are triggered every time you cast a creature with power 5 or greater. Earthquake Dragon and Primeval Protector pull double duty here, constantly bouncing each other back to your hand thanks to Brinelin, the Moon Kraken's ability to sweep away a nonland permanent whenever you cast a spell with a mana value of 6 or greater. As you repeatedly recast these giants, Primeval Protector even sneaks in an extra +1/+1 counter on every other creature you control on each entry, snowball utilidad alongside your infinite storm count and endless creature triggers.
