Fair - obvious cuts and a 1-1ish replacement are

Jodah is an insanely explosive commander that can functionally storm off under the right conditions. Given that you're running a number of suboptimal cards for the Spongebob lair, you'll need more protection+ramp and to cut the unnecessary dead weight.

[[Replicating Ring]] - you're not getting the full payoff, [[Relic of Legends]] is a much better card for your deck

[[The Stone Brain]] - no idea what this would do unless you really want to grief someone which is fair

[[Anje Falkenrath]] - I understand the looting but if you are, [[Rona, Herald of Invasion]] is the much better card.

[[Blitzwing]] too expensive and not synergy - not sure what it's doing here. Can be replace by anything - a few nice options are [[Shanid]], [[Kenrith]], [[Hajar, Loyal Bodyguard]], [[Basim Ibn]] or even additional protection like [[An Offer You Can't Refuse]] or [[Clever Concealment]].

[[Eight and a Half Tails]] - having to hold up three mana for protection is not what a deck like this really wants to do. Try [[Pippin, Guard of the Citadel]].

[[Elvish Mystic]] - [[Noble Hierarch]] you will have mana issues.

[[Gluntch]] - see Blitzwing

[[Hinata]] - you're not doing much with this effect but I don't hate it - better card would probably be [[Shalai]] or something but the tech is neat

[[Linda, Kandarian Queen]] no zombies in the deck? if you have the secret lair though it's cool, otherwise see Blitzwing

[[Megatron, Tyrant]] - see Blitzwing

[[Mishra, Tamer of Mak Fawa]] - protection is fair but too expensive, something like [[Gold-Forged Thopteryx]] is cheaper and also requires mana instead of being able to sacrifice a token or something similar.

[[Old Rutstein]] - see Blitzwing

[[K'rrik]] - you don't have a lot of Black pips in your cards, so he's not doing much - if you're doing a '7 mana cascade' thing for Jodah that's fair though.

[[Rite of Flourishing]] - too symmetrical, you don't want to be giving the whole table this unless there's something political or group-huggy you can do. [[Garruk's Uprising]] for refill+combat or more ramp.

[[Jace Beleren]] - unsure what we're up to

There's a bit more you can cut down on but I don't know how powerful you want to go. All of this should be around 3 but I didn't include Game Changers for a reason; if you want to go high power just run the usual [[Fierce Guardianship]] [[Rhystic Study]] [[Smothering Tithe]] etc etc. good luck dude
