It also allows you to show that you arent a threat
Red Eyes Flare Metal is one of the best rank 7 XYZ monsters in all of Yu-Gi-Oh, in Red-Eyes decks and others
Isamaru can make a formidable Voltron deck as well, with its low cost for a 2/2, throwing great equipment and auras at it can quickly overwhelm your opponents if they can't deal with it quickly, or let it sit thinking it's not that big of a threat
The mana value is what holds it back, which will be the case for all of these, but at least one of these Gearhulks feels like it should be breakable
