Loading up your creatures with counters
I think this works especially well as a defensive card, as it can bait attacks from larger creatures only to then overpower them with an instant that boosts its stats, which also gives it first strike
Because it became possible to access Trap Monsters, in other words, Conquistador, from the deck
They should avoid using "lord" or "anthem" effects, however, to make sure their own creatures don't permanently have power 3 or higher
This effect can be used only once while this card is face-up on the field.
And even though the card Judge from the Sword & ShieldFusion Strike expansion has an E regulation mark (which has rotated out of the Standard format), it can still be used because the card Judge from the Scarlet & Violet expansion has a G regulation mark
