what is a break card in pokemon - Chesnaught-Break (12/162) Delphox BREAK retains the attacks Pyroar BREAK | XY—Steam Siege

Cosmic Eclipse also introduces new mechanics such as the Fullmetal Flame and Spiraling Cut Abilities, as well as a number of new powerful attacks such as the GX attacks

Favor of the Mighty works especially well because Blind-Spot Giant and Borderland Behemoth care about the other giants you control, but they dont specify giant creature. That means that the enchantment counts, letting your Blind-Spots attack more easily and buffing your Behemoths even further

You also get a free random custom token, so thats cool too

The card is at its best in more aggressive strategies that seek to use their graveyard to some advantage
