• Effect: Retain. Discard your hand. Draw cards equal to the number discarded. Exhaust.

A powerful cost-0 Skill that refreshes your entire hand and Exhausts, so it won't clog your deck again. Functions as a total hand reset when your hand is bad. Being single-use, that one use often swings the game. Playing it while holding multiple Sly cards triggers all of them at once for a huge combo. Upgraded gains Retain, letting you hold it across turns for optimal timing.

• Play it when your hand is poor (too much Block, not enough attack, etc.) to fully refresh.
• Holding multiple Sly cards like Flic Flac or Choke and playing Cheat triggers all Sly at once for a strong combo.
• Since it's Exhaust, don't hesitate at the right moment. Upgraded Retain lets you pick the best timing.
• With Memento Mori, discarding your whole hand massively boosts damage (Memento Mori must be in the redrawn hand).
• Played during Corrosive Wave, the redrawn cards each apply AoE poison — an extremely strong combo.

• Corrosive Wave: AoE poison on each draw this turn. Redrawing 5-7 cards with Cheat applies poison that many times.
• Flic Flac (multiple copies): Sly AoE attack. Discarding several with Cheat triggers them all at once.
• Memento Mori: Deals 4 extra damage per card discarded. Massive damage after discarding with Cheat (need Memento Mori in the new hand).
• Afterimage: 1 Block per play. One cost-0 Cheat still grants 1 Block.
