I think 1|1 and 2|2 is good. There are a plethora of ways to kill it: Immolation, Devour, Ice/Fire Bolt, Lightning, poison, Liquid Shadow, Gravity Pull. In fact, I think using BB and GravPull is a nice combo. It takes three cards, but prevent a bit of damage and gives you a pillar/tower in the end. Devour is an easy option, you can get a bit of a hit, then eat it to combine its strength into a unit and get a Pillar out. Its actually a pretty handy card when you compare it to Photon.
