Shieldmage Elder

Onslaught built two activations into one elder, each priced not in mana but in the bodies of a tribe you were already supposed to be fielding. Tap two Clerics and a creature's combat output disappears; tap two Wizards and a damage-dealing spell's damage is prevented. That dual-tribe gating is the whole design conceit: this is a payoff that only functions inside the Cleric and Wizard subthemes the set was selling, and it asks you to commit to both at once to unlock everything it offers. The damage prevention itself is broad. The creature clause stops any one creature cold for a turn, which neuters an attacker or a blocker; the spell clause answers burn and other direct-damage effects at the source rather than the target. What pays for that flexibility is the convoyed cost. You are tapping down two creatures per activation, so every shield you raise drains your board's ability to attack or block, and the elder itself does nothing without a wide, tribally-aligned table underneath it. The result is a control fixture for a deck that was never quite assembled: a defensive value piece for a Cleric-Wizard hybrid that wanted to grind the long game on prevention. The 2/3 frame is incidental; the card is a tap-engine outlet, and it lives or dies on whether you have enough of the right creature types standing to feed it.
