Another deck build based off a tweaked version of a budget build by Hexxen. His original decklist can be located at https://eternalwarcry.com/decks/d/akw8aZE_bYY/budget-relic-swarm.
As I was looking over this deck and preparing to post it I had a thought that I should switch
Xumuc Coercion for
Coveted Gemstone. Sometimes you can get stuck on power and not be able to do enough, plus it hits every card in the market and can also trigger Rat Cage or be used as fodder for Lethrai Lobotomy if necessary. I found
Oblivion Spike very useful if you were expecting a board wipe after a big attack.
Amber Ring I found it useful against removal piles to just keep playing things out.
If you like this style of deck and have a larger collection or more shiftstone, you may want to check out :
