Machamp

Poké-PowerTerraforming

Once during your turn (before your attack), you may look at the top 4 cards of your deck and rearrange them as you like. This power can't be used if Machamp is affected by a Special Condition.

Count the number of Pokémon you have in play with damage counters on them. Flip a coin. If heads, this attack does 50 damage plus 10 more damage for each of those Pokémon.
