I think twn2dn generally ahs teh right of it here. I see where you're coming from in the big picture, Drakey - but playing Bara Rush and various iterations of Targ have left me mostly invulnerable to Venemous Blade. Although it hasn't been a decisive factor in any game I have been in for the past year and a half - given the lack of attachment control I can see how it is perceived as a stronger card at the moment.
But Burning has cost me far more in terms of wins and losses and I think its more powerful. It certainly is recursible, its certainly searchable (and given the At the Gates + Luwin combination - its even more readily at hand) Surely I mis-read you twn2dn: you aren't suggesting that BoTS NEEDS to remain in teh environment to keep Martell competitive as the pool epands? Don't they have enough, appropriately costed options right now? Surely a free challenge cancel surprise card, one that eliminates ALL ramifications of a challenge while keeping the attacking characters knelt and unavailable is a bit much for a Hosue already specializing in card advantage and denial effects? If you are saying this card is likely to grow stronger as the pool expands - I agree with you. Quite frankly i find that an alarming thought, given how strong it already is.
Its a bit frustrating to think of how many overpwoered effects like his Martell has enjoyed for the past few years, and how long it takes R&D to address them. Here's looking for a Locked in the Tower reprint in the future. It certainly wouldn't surprise me at this point.
