Cannot be activated, except at the start of your Main Phase 1. Cannot be destroyed or targeted by card effects. Neither player can Set cards. Both players can activate Trap Cards and Quick-Play Spell cards from their hand. Each player must remove a number of Mana Counters on their field equal to the Spell Speed of a card they would activate (cards with "cannot activate cards or effects in response" in their text are treated as Spell Speed 4) or Level, Rank, or Rating of a monster they would Summon. Once per turn, the turn player can reveal 1 monster in their hand, and keep it revealed until the End Phase to place 1 Mana Counter on themselves. Once per turn, the turn player can place a number of Mana Counters on any card they control equal to the number of Mana Counters currently on themselves.
Get dunked on, literally everyone, we playing MtG now. Simplified rules, obviously, but good luck surviving to the point that you can actually make an ED monster (at minimum, it takes 4 turns to make a Link-4). A half-decent Level 3 or lower beater can utterly crush most game plans by virtue of being difficult to counter under this, because nobody runs wall monsters anymore, unless your opponent specifically saves up Counters to drop a bigger monster (by which point you can also probably beat over their thing). Welcome back to caveman YGO for a good few turns, if you get this turn 1.
Along the lines of Number Wall giving Numbers the Number Clause, create a Spell/Trap that conveys the missing anime effect of a monster that got neutered IRL. Try your best to make it narrow enough to avoid abuse without outright naming the thing you're trying to give back its glory. Examples:
•REDMD gaining its ability to negate Spells and its 400 boost per Dragon in the Graveyard.
•Blue-Eyes Shining having the ability to pick and choose which effects work on it and a Quick field nuke during the Battle Phase.
•Meklord Astro Mekanikle could negate monster effects so long as you had a monster card on hand and a Synchro existed in a visible space, and could revive Meklords ignoring their Summoning conditions.
•Starving and Greedy Venom both did burn damage when they nuked the field, and negated the effects of monsters whose effects they copied.
