I haven't used it since xyz's got introduced so I'm not sure what I need to do to improve my deck
-1 Spear Soldier
-2 Visionary
-1 Solidarity
-1 ECon
-3 Magician's Circle
-2 Rite of Spirit
+1 Commandant
+2 Royal Tribute
+2 Gravekeeper's Steele
+1 Solemn Judgement
+2 Solemn Warning (if your budgeting, then Black Horn of Heaven would be a decent substitute)
+2 Seven Tools of the Bandit/Dark Bribe (either or)
Visionary will most likely be a dead card, since you'll be tributing your Recruiters/Spys for Descendant instead. Spear Soldier, piercing is nice and all, but otherwise it's ehhh.
Most Gravekeeper decks I know dont run Guard, but I dont see a real reason to remove it. Bounce isn't a bad thing to run, since it screws over Synchros/Xyz's, and 2400 Def after Necro isnt that easy to penetrate.
Solidarity isn't necessary. On average, you'll have attackers ranging from 1700-2100 as it is. It's also another dead draw. I'm not exactly sure about ECon either, but thats probably because I just dont like the card to begin with. If you wanna keep it around, you're not doing yourself any harm.
Rite of Spirit. Idk, I've never found more than one to be required, like ECon, you're not exactly missing out on anything, but that space could be put to better use (since Steele will generate more pluses than Rite). Magician's Circle is way too slow.
Also, don't let the kids fool you with Wonder Wand + Recruiter. In my experiences it's an average combo at best.
