More Than Meets the Eye (You may cast this card converted for .)
Double strike, haste
At the beginning of each opponent's upkeep, you may have that player gain control of Slicer until end of turn. If you do, untap Slicer, goad it, and it can't be sacrificed this turn. If you don't, convert it.
Living metal (During your turn, this Vehicle is also a creature.)
First strike, haste
Whenever Slicer deals combat damage to a player, convert it at end of combat.
Slicer is a mono-red Voltron beater with double strike and haste that you cheat into play for and load up with equipment and combat triggers. Each opponent's upkeep you can hand them control (untapped, goaded) so it swings at someone else, or keep it as a Vehicle artifact—either way Slicer is almost always attacking, often for 2+ commander-damage chunks per swing thanks to double strike. You win by stacking damage doublers, extra-combat effects, and equipment to take players out fast while the goad mechanic keeps the table fighting itself.
Double strike + haste means commander-damage kills come terrifyingly fast (as few as two connects with a couple buffs).
Cheap to deploy at and recast efficiency keeps it on the battlefield even after removal cycles.
The hand-it-off-and-goad ability turns your commander into a political weapon that attacks your opponents for you.
Mono-red gives access to the best aggressive ramp, equipment, and burn finishers.
Giving away control is risky—opponents can buff or sacrifice-protect it, or use it against your other threats.
Single-target removal or counterspells on a Voltron piece set you back hard.
Mono-red lacks card draw and recursion compared to other colors.
Goading is unpredictable; the table may direct it where you don't want it.
