That's a three card combo(plus the Catapult/Trebuchet), from three different elements(two if you use Animate Weapon instead). Technically you could run the Freezes off your mark, but you still need the pillars and turns to accumulate the quanta for the Titan, Trebuchet, and activate the skill. If you're going for a kill, you have to do this twice. So, with optimal draws, this would be good. But not OP. Not even close.
