Tithe Taker

The tax only applies during your turn, and that asymmetry is the entire point. A generic Sphere of Resistance effect punishes both players equally; this one leaves your own combos, your own end-step activations, and your own interaction untouched while making an opponent's attempts to respond on your turn one mana more expensive. It taxes exactly the window where a control opponent wants to hold up a counter or a flash blocker: cast your key spell into it, and their answer suddenly costs more than they planned for. The 2/1 body is deliberately fragile, but the Afterlife 1 clause means killing it is not free tempo for the removal spell; the flying Spirit that replaces it keeps evasion on the board and keeps the trade honest even after the card is nominally dead. That pairing (a proactive taxing effect stapled to an aggressive two-drop that leaves something behind when it dies) sets it apart from the pure prison pieces its ability recalls. It does not lock a table down the way a symmetrical tax does; it buys a turn's worth of protection for whatever aggressive or combo-forward plan you are already running, then leaves a flier behind to make the removal feel wasted. A hatebear that also happens to attack, priced so that neither half is the tax you pay for the other.
