Infinite Combo

An infinite combo is a setup that allows you to keep playing the same cards forever in a single turn, either spending no or continually regaining the energy used. Infinite combos are powerful as they allow you to keep attacking until you win the battle, keep gaining until nothing can harm you, or keep gaining energy to spend it all at once on a cost X card.
As most infinite combos work by continually drawing the same cards, the setup requires you to have very few cards in your draw and discard piles. This is helped by avoiding adding cards to your deck other than core cards in the combo and removing them whenever possible. Cards that and Power cards may still be used.

The discard pile must contain a card, usually an Attack, that allows you to draw the multi-draw card again. If the multi-draw card can draw more than two cards, you can include some additional extra cards in the combo.
