Bifrost is incredibly powerful. If you haven't played a bifrost deck, you should try summoning a valkyrie out of your deck. Thor's kit is secretly rich thanks to his God of thunder upgrades, and bifrost effectively reduces the cost of asgard allies. All the asgard allies are really good when you can play them out of your deck.
On a quick search on Marvelcdb, Valkyrie ally is present in at least near 1800 decks... I always include her in Asgard themed decks and in several aggression deck. So strong and convenient. Thanks for the video!
I think there may be allies who are more 'Value-able' than Valk, but I think Valk is still great because she gives you a huge tempo boost. In the right circumstances she kills two minions instantly and stays on the board for another turn. Magik or Thor could do something similar but you need to pay an extra resource. Overall I think she is awesome and I usually put her in my aggression decks esp. against minion heavy villains or heroes who like energy resources. (Thor, Cap Marvel, Iron Man, etc)
I'd argue she's even better peak value as 2 damage for 1 er is top end rate - usually it's closer to 3 for 2. Also 3 and 2 is usually better than 5 in one chunk. Efficiency and tempo all in one package! She is certainly very good. I do not use her all that much for various reasons often it's playing a tribal deck where she does not fit. Other times it's because she does lots of damage which aggression has any number of ways to do. I am often looking for chumps and threat removal from my allies. Threat is usually charged by the game at 1.5 time as much as damage so Brawn can do 12.5 worth of damage, kinda, best case, though with terrible tempo. If I am chumping a lot the 2 cost allies can be more efficient than her or Thor/Throgg can get a tough block. So my guess as to why she's not talked about much is that she does not do something you can't do another way in aspect. I do like her with the Valkyrie hero and Bifrost means you can make sure to summon her for one less and when she is definitely going to get full value. (There are 9 Valkyries after all - how do we know the ally is Brunnhilde? If they publish another Valkyrie hero who is Skuld, say, then how would be know which hero the ally was not supposed to go with?)
In a recent ally tier list video, the content creator had her B tier. Which I think accurately represents the general sentiment. Noone think she is bad, but is never in conversation of must run, best, or super efficient and I rarely see her in decks. So yeah, I agree she is considerably better than is given credit for.
