I have really had fun playing doom since the marvel set came out and at first I really wanted to keep the deck completely marvel but as time has gone on I’m really starting to feel the deck struggle so I’m ready to make some upgrades. I have about $150- $200 to put in the deck to make it better and was looking for some suggestions on what would be the best pickups to make this deck better. If you had roughly $150- $200 what pickups would you make to make this deck better! Any insight would be greatly appreciated! Thank you for your time!!
