I periodically even see industry professionals on these groups, so they must be doing something right
Youll be able to see your opponents hand, choose a card, and tax it, whether they're casting it or using its non-mana activated abilities

Im not saying Sea Gate Wreckage will transform Affinity, but I definitely think its worth exploring
