This is a fairly simple discard combo deck. The main idea of this deck is to combo Hela with Invisible Woman so we can hide our discard cards and finish off the game on turn 6 with Hela reviving all of our discarded cards.
The way you want to play out this deck is to usually hide your discard cards behind IW. However, a lot of the times (especially in higher ranks) your opponent will know that combo and he will try to punish you with the likes of Cosmo on your IW location or silence IW with the likes of Enchantress or Rouge in order to mess up your combo, so you have to be very wary of that.
Another thing to note is that your have to take risks and understand your Hela might get discarded, in the case that happenes your opponent will usually snap at you thinking you have no other plays which is exactly where Ghost Rider comes into play. Ghost Rider can help us by bringing back Hela and the cards discarded alongside with her, we can also double down on that effect with Absorbing Man on the turn after you've played GR so we get to revive two discarded cards.
Most of the cards here are flexible but the ones you have to play are Sif, Ghost Rider, Invisible Woman and Hela.
I highly reccomend on adding Death if you have her because she costs 9 which means Sif will always discard her and not Hela. The thing you have to understand about Sif is that if she sees you have multiple 6 cost cards she'll discard one at random which means she can also discard Hela herself, so in case you don't have Death in hand it's better to use cards such as Hellcow or Sword Master so you'd have a chance of not discarding Hela.
