Flip 2 coins. This attack does 10 damage times the number of heads.
Beat Up ふくろだたき
Flip a coin for each of your Pokémon in play (including Sneasel ex). This attack does 20 damage times the number of heads.
Each of the Pokémon-ex in EX Ruby & Sapphire seem to be based on popular cards from pre-EX Series sets. This card in particular appears to be based on Neo GenesisSneasel, a card which was banned in some formats due to the power of its Beat Up attack. What balances out this version from being overly effective is that it requires an extra Colorless Energy, and is on a Pokémon-ex card (which are worth two prizes when Knocked Out by the opponent).
