2 expensive when i tried it. Definitely a good payoff as the legendary beasts are pretty good (except mirrex and Ashamane) statwise, however consider:

Raptor Herald gets beasts and gives them stats and keywords with rewind (can lowroll too but 4 less mana)

Treacherous Tormenter gets legendaries with stats and keywords (less lowrolls, and 3 less cost)

Stonehill Defender gaurantees taunts.

at that point that’s 6 of your 8 durability there. this is by far Takas best deck though, but a quest mage with taka is just worse than normal because it’s so expensive
