Graviton strategy.

[918273645]

  Graviton's creatures have little HP, so Oty does some good. Eagle Eyes, Fire Lances, Rains of Fire, and Ice lances, help reduce health. Then you send in your Oty. After a while, you don't even need the help. ALWAYS eat the creature with the highest attack.

Graviton's creatures have more health then yur Oty Does. if you dont RoF and eat, you can die easily. Stealing a Gravity Shield will really help against their non momentumed creatures. Gotta be careful of Momentumed Otys that can kill yours.

[icybraker]

Steal his Gravity Shield to block against the brunt of the attack (Firemasters). However, this will not shield you forever, because he has Momentum. Fire Storm and send your Otys in to eat creatures, or just Fire Storm twice with a Bonewall or a Graveyard up. If you have Lobotomizer or Mind Flayer, you can get rid of Momentum. Be wary not to let the Otys touch your creatures; don't play a Graveyard if the opponent has Otys out. Remember, you can eat your own creatures to swell your own Oty to a large enough size to eat all of Graviton's creatures. Mutant spam should be able to finish him off.

shouldn't you also put some blessings in your deck to make your otyughs powerful enough to eat his more powerful cards?

Quintessence + Elite Oty makes his creature control negligible. Use Lightning Bolt to take his Firemasters down to eating size, then proceed to eat the rest of his team. Lobo helps too. If you really have to have some permanent control, Mark of Fire for Explosion will do the trick.
