Saw Chance Encounter and it looked like a fun card to build around!
4x Chance Encounter- The primary win condition of this deck, add counters by winning coin flips! Playing multiples to make it easier to find, but could be reduced.
4x Goblin Bomb- Alt win condition that helps to enable Chance Encounter! Multiples allow multiple "at the beginning of your upkeep" coin flips, which you use before Chance Encounter does it check for a potentially sneaky win.
4x Krark's Thumb- Increases my odds of getting wins on my coin flips, four because it is important it goes down turn two.
4x Karplusan Minotaur- Freaking amazing card. The longer it lives, the more coin flips I get. And did I mention that they are "at the beginning of your upkeep" coin flips?
4x Mijae Djinn - Cheap to cast 6/3? Yes please! What I like about him over other coin flip creatures is that he doesn't die if I lose the flip.
4x Gamble- Lets me search for any missing pieces I need in my starting hand. Plus it fits the theme of "Luck".
4x Fiery Gambit- Lets me press my luck and flip flip flip!
4x Game of Chaos- More flipping!
4x Volt Charge- Mainly in here for the proliferate, which is great on either win condition. The three damage is a nice bonus.
4x Tezzeret's Gambit- More proliferate that can be played in mono-red!
