The Smash hacks using Gigantuar's Feast as hero power

I have encountered a player who was playing The Smash, about 30 minutes ago, in a Ranked Match using Gigantuar's Feast as hero power while blocking. I don't know his username because I don't always pay attention at the beginning of matches. I'm confident that he is hacking by manipulating the game data on hero powers. While I would normally appreciate a good match whether I win or lose, this has really ruined the fun and fair experience I was expecting. Hacking really shouldn't be tolerated at all.
