Tier 0 (PLZ NERF):
Sith Holocron: Due to blue abilities being generally underpowered, Holocron is effectively less than tier 0. However, in a vacuum, having 2 Four resource sides on a 0 cost die is out-of-this-world good.
Tier 1 (Amazing):
Crossguard Lightsaber: This is only a tier 1 in a Kylo deck, without Kylo it’s tier 2.
Tier 2 (Solid):
Kylo Ren’s Lightsaber
Kylo Ren’s Starfighter
Tier 3 (meh):
Force Lightning: This card is effectively tier 1.5 in a deck with both Holocron and Rise Again.
ID-9 Seeker Droid: This card is tier 2 with Seventh Sister.
Lure of Power
Grand Inquisitors Lightsaber
Command Shuttle: In theory having 2 special sides that are equivalent to a special on one of your characters could be extremely busted if the right character pairing can be found.
Tier 4 (Putrid):
Darth Vader’s Tie Advanced
