Trainer Cards are split into two types primarily: Items, which you can use as many of as youd like each round, and Supporters, which you can only use once per round
Maybe you could use OR (like this, with capital letters), but I think my suggestion avoids any problem you could have, and final clause was changed so you can only use 1 effect per turn even if they're separated
Immediately after this effect resolves, Link Summon 1 Fiend monster using that target and 1 "Unchained" monster you control as material
Along with retro frames, there's also a serialized movie poster style, but I really like this version, which looks more like a portrait this character might actually hang on his wall
Both cards captured the flavor of transformation and each definitely played a different role once it was changed
