I myself am an F2p player and have never spent a buck on this game and it pleases me immensely when I see HHG decks get thrashed because of this skill.. and HHG has broken the meta game.. platinum is infested with HHG-Harpies and HHG-relinquished. This skill also deals with the pesky burn decks as you can get a one turn 🔥 with double summon.
I spent a lot and spent as best i could the gems, but when i got this skill, i had more chances in pvp, plus anyone can have it, and isn't hard to counter
