Why are all the progression taskmasters red, with a red HFH? Your boy has a 3/2/2, need to spread that color love around some!
Just buy out the anniversary vault three times (or as much as you need to get the black and blue covers from the vault). Together with the free tokens during the event plus HP in the vault itself, it'll probably only cost 45-50k HP.
Alternatively, just treat it as any other limited character: you will very rarely have a reason to use the character, so treat it as a trophy. It's only worth spending iso on them if you don't have anything else to spend the iso on, so fully covering them is a luxury.
Are the developers or whoever having a nap... boosted for yet another alliance event is hulkbuster... been a few times in a row now.. pretty sure wolverine xforce had been a few as well. Without scrolling back I’m thinking mockingbird in the last one... where is the variety? Alliance events had always been a great way to test out new teams and characters.. now it’s getting boring
