■ [Cast Cost] [Pay 2 gauge] ■ [Counter] You may cast this card when an opponent calls a size 2 or less monster. ■ Nullify the attack.
Q2321: I declare the call of "Topfist Vainglory, Brawlzeus" while my opponent has exactly 2 Gauge. Can my opponent cast "Begone!!" in response to my call?
A: No, they can't.
The [Counter] Timing for a call occurs after all costs have been paid.
When you pay the [Call Cost] of "Topfist Vainglory, Brawlzeus", your opponent will only have 1 Gauge remaining, and they will not have enough Gauge to pay for "Begone!!", so it will not be able to be cast.
