Trojan Gladiator Beast allows you to Special Summon 1 Gladiator Beast monster from your Hand to your opponent’s Field, and draw 1 card. Therefore you can use Gladiator Taming to regain control of that Special Summoned Gladiator Beast monster.
Samnite, sure. But I wouldn't expect the others any time soon. (I'd have said War Chariot was a possibility, but we just got Equeste.) What I don't get is why we don't have Lanista or Torax yet, since they're both pretty weak. (Torax really should've been a Common in the current Duel Island.) Test Tiger could probably happen soon, actually, too.
You know, that Trojan trap card is 🔥? First you need to set it, that make it prone to destruction/banish, second you need to wait a turn, third you need a GB in your hand and 4th you need this card. And this all for WHAT? That you end with +0? Way to much setup for no real benefit(especially when you consider a defensive/offensive use of Taming).
This can be a dead card. While first effect is easier to accomplish, you are way more vulnerable to not being able to use it during enemy. Outside of a mirror-match tricky to use... Especially second effect is impossible to use then. Only good thing is you don't need to tribute for second effect = able to use enemy GB for extra deck or attack+GB from your deck.
