Ray Fillet, Man Ray + Berta, Wise Extrapolator + Heartstone + Wizard Class

Ray Fillet, Man Ray

Berta, Wise Extrapolator

Heartstone

Wizard Class

How it works

1. Activate Ray Fillet by paying 1 due to Heartstone and removing a +1/+1 counter from a creature you control, causing you to draw a card.
2. Wizard Class triggers, putting a +1/+1 counter on Berta.
3. Berta triggers, adding 1.
4. Repeat.

This clever engine centers around converting a single +1/+1 counter into a fresh card and back again, looping indefinitely to churn through your entire library. Ray Fillet, Man Ray drives the core interaction by letting you cash in a counter to draw a card, an ability made far more efficient thanks to Heartstone reducing its activation cost. Berta, Wise Extrapolator and Wizard Class act as the ultimate catalysts: every time you draw from Ray Fillet's ability, Wizard Class triggers to place a replacement counter right back onto Berta, which in turn triggers Berta to effortlessly generate the exact mana needed to pay for the next activation. With Wizard Class also ensuring you have no maximum hand size to worry about, you can easily hold your entire deck and sculpt an unstoppable win condition.
