I loved the character phantasm from some books! It's a shame that is character is weak (very). Can anyone think of a way to break him (or use him at all).

Take part in stubarnes challenge 4..and someone may jst find the key to breaking phantasm..

When I read Phantasm's effect it seems like a very situational and tough effect to get, by the time you get 10 TT's in your KO'd pile youd prolly be dead...

it would be hard
but im sure it'll be easier when future sets come out

right now you can use:
shape change
tamaran
titans tower
optitron
doom's throne room (might help)
negative zone

and if you teamed up:
cerebro
x-corporation

if only you could use Overpowered on yourself....:p

what did he do in the comics?

Yeah. Play Phantasm on turn 7 when you have initiative with boosted Tim Drake. Since you should have 2 other characters on the table, this is generally enough to win the game.
