Family's Favor

The shield counter usually shows up as a defensive line: a one-shot ward against removal or a blocked-damage save. This enchantment repurposes it into an attack-step engine, and the reroute is the whole idea. Every combat, one attacker gets a shield counter, but the counter is loaded with a rider: connect and it cashes itself in for a card. So the same token that protects the creature also draws you the card, and the two uses compete. You can bank the counter as insurance and eat the removal instead of drawing, or you swing into a clear board and turn the shield into a repeatable Curiosity that resets every turn. The green framing is unusual too: card draw off combat damage is more a blue habit (Coastal Piracy, Bident of Thassa), but here it rides on green's comfort with counters and wide attacks rather than on evasion. Because the trigger fires whenever you attack and targets any attacking creature, it rewards a board that presents multiple threats and lets you point the counter at whichever one is hardest to block that turn. What gives the card its shape is that the reward and the protection are drawn from the same well: every combat, you decide which of the two you actually need, and you cannot have both.
