More Than Meets the Eye (You may cast this card converted for
.)
Your opponents can't cast spells during combat.
At the beginning of each of your postcombat main phases, you may convert Megatron. If you do, add for each 1 life your opponents have lost this turn.
Living metal (During your turn, this Vehicle is also a creature.)
Whenever Megatron attacks, you may sacrifice another artifact. When you do, Megatron deals damage equal to the sacrificed artifact's mana value to target creature. If excess damage would be dealt to that creature this way, instead that damage is dealt to that creature's controller and you convert Megatron.
Megatron is a Mardu artifacts/damage deck that punishes opponents for losing life. Lock combat down with the tyrant side's spell restriction, then attack, sacrifice artifacts to ping creatures and bleed players, and on your postcombat main phase convert to Destructive Force to generate massive colorless mana off all the life lost this turn. Funnel that ramp into big payoffs while grinding the table down with incremental damage and recursion.
Add fast mana and artifact engines (Mox Opal, Mana Crypt, Sol Ring, Krark-Clan Ironworks) to deploy and reload sacrifice fodder, plus token-makers like Servo and Treasure generators for endless fuel. Lean into aristocrats payoffs (Disciple of the Vault, Mayhem Devil, Bastion of Remembrance) so each sacrifice closes the gap on its own. Top-end the mana sink with reusable wraths or big X-finishers, and include tutors (Goblin Engineer, Whir of Invention, Demonic Tutor) to assemble the engine consistently.
