|Ability||Opening Gambit: Gain the combined Attack and Health of all Battle Pets in your action bar.|
- Calculator gains buffs immediately, which makes it safe to play it with Flash Renicarnation or Kujata, because the damage applies after the stat buff.
- Since Calculator's mana cost changed to 4 mana, the card's power level increased a lot. It can provide a very strong turn 2 threat which many decks have problems to answer. Nevertheless the card has some disadvantages. It is slow, not doing anything on the turn it is summoned and it not only requires you to play battle pets (which is really bad in itself), but to have a good amount of them in hand. Also Dispel is an easy answer to it.
