Ive heard people claim this is testing way better than expected, especially in white devotion decks, and that on an aggressive board it basically gives you a giant threat that must be dealt with twice
That means that if you play Frodo, Determined Hero when Swiftfoot Boots is in play - which grants hexproof and haste - you can attack straight away and it cant be targeted, and the attack will trigger the effect again, allowing you to put another equipment card on the Ring-bearer
In fact there are examples of cards that could be considered strictly weaker than others that gain power with the right build (ie: Diabolic Intent vs Demonic Tutor in an Aristocrats style deck)
Hey, you asked for more transparency, so theres a good window into my head (note that the rest of the RC may not share my views on this particular subject)
