Hedron Blade

A hate card wearing an Equipment's clothes. The deathtouch clause reads as anti-Eldrazi tech, and it was born in an era when colorless-matters creatures were a real lineage on the board, but the trigger doesn't care about pedigree: it fires against any colorless blocker at all, from the giant colorless walls that inspired it down to whatever colorless artifact creatures happen to be gumming up the ground. Against that slice, a point of damage from your wearer becomes fatal, so even a small attacker trades up into anything that dares to block it. The trouble is the chassis carrying the rider. Casting this and then paying to attach it, all for a +1/+1, is a thin rate that nobody wants for the buff alone. So the whole card lives on the conditional. When the opposing board leans colorless, the deathtouch converts an overpriced piece of Equipment into a real combat answer, letting your weakest body punish theirs. When it doesn't, you are holding a slow, forgettable stat bump. That is the honest shape here: a narrow hoser whose floor is too low to run on its own merits, so its worth swings entirely on whether the specific board state it was built to punish ever shows up across the table.
