Thick-Skinned Goblin

The whole point of this Goblin is a discount that exists for exactly one mechanic and almost nobody else's. Echo was a recurring tax: a permanent with echo costs its mana again on your next upkeep or it dies, which makes the early cheats feel like loans rather than gifts. This Shaman erases that second payment entirely, turning every echo creature you control into what its first cost suggested it was. The protection-from-red ability is the strange companion clause, and it reads as a self-defense valve more than a plan: it lets the body survive your own red sweepers and dodge red removal, but it does nothing to advance the echo discount that justifies the card's existence. That split is the design tension here. The waiver is build-around and narrow, useful only to a player who has stacked their deck with echo permanents and wants to skip the recurring tax across the board; the protection is generic insurance bolted on so the creature is not a complete blank when the echo synergy fails to materialize. It is a piece of enabler design from an era that liked to print mechanic-specific payoffs at common-adjacent rarity, betting that a critical mass of echo cards would show up to make the discount matter. That bet defines whether this is a quiet engine or a 2/1 that occasionally pays to ignore your own Pyroclasm.
