I have a question sir!
Why is Double time better than Bowling Ball? Bowling Ball seems much better considering that wrecker is way weaker than cauterize, and also comes out instantenously for a much clutcher save?
Theoretically, that argument is sensible, however in practice it doesn't really work that way.
The issue with Bowling Ball is that you don't even need Wrecker to deal with it. In the days it used to be good it actually made you get Wrecker for it. But now most characters that do half decent damage can just shoot at it with no Wrecker and poof the shield is down. Cauted Double Time will still provide sustain while it's healing you 20/sec at Caut 3 instead of Bowling Ball where you just lose all the sustain from the card when the shield is destroyed.
And even then it isn't like Cauterize increases the damage dealt to health like Wrecker does to shields. If Caut did that, then yeah Bowling Ball likely would be straight-up better because you'd have to burst it down. But both would suck at that point and Caut would be busted.
