This is my budget deck pool 2 deck if you want to use the free Nick Fury and like some RNG.
The main issue with using him is that if you don't use a swarm deck, your hand can often be too full to get all 3 6-cost cards. For this deck, the main point is to get cheap cards onto the field and keep tempo with Nick Fury as an RNG type of finisher, since I find it pretty fun to pull a win with cards out of nowhere. The way I play this is to focus first two turns with any one or two drop in the same lane, besides bucky and carnage. They serve as carnage food and you play those two on turn 4 for a power boost in that lane. If you don't draw carnage, you can use Killmonger to trigger Nova. Turn 3 is usually a morph or to empty my hand to use Carnage and another 2-drop.
Bucky is also good to hold to contest death locations like altar of death, bridge, or death's domain.
White Queen is also essentially a backup to copy your oppponent's win-con if you don't draw fury or manage to empty your hand by turn 3.
Have fun!
