Teferi's Sentinel

Golems are usually colorless mercenaries, equally at home in any deck, but this one writes a loyalty test into its rules text. Without a Teferi planeswalker on your side, it is a 2/6: a wall, a blocker, a body that soaks attacks and adds nothing to the clock. Find the right Teferi and the same golem swings as a 6/6, the defensive lump becoming a genuine threat. The whole design lives in that conditional: a payoff whose ceiling only exists once you have already committed to the right legend. The five-mana price and the lopsided base body signal which half of the equation the designers expected most players to occupy. As an artifact creature it sidesteps color identity entirely, so any Teferi deck can run it regardless of colors, which is the concession that stops the requirement from being prohibitively narrow. This is a flavor-first reward: the planeswalker's personal construct, stronger while its master is present, dull when he is gone. Cards built this way exist to make a named character feel like the beating heart of a deck rather than a top-end finisher, and the toughness-heavy default body is the safety net for the turns the condition is not met.
