Bestial Fury

Stapling a combat trick to an Aura is a harder design problem than it looks. Most pump auras lose you a card the moment your creature dies, and the opponent gets to decide whether to make that trade by choosing how to block. The delayed card-draw clause answers that risk: it refunds you a card at the start of the next upkeep no matter what happens to the enchanted creature, so committing the Aura no longer means staring down a two-for-one. The trample-on-block trigger does the offensive heavy lifting. Instead of a flat buff, the bonus only fires when the creature is blocked, which turns the enchanted body into a question the defender cannot answer cleanly: chump it and eat trample damage, gang-block and lose two bodies, or take the swing. The +4/+0 is sized so that a lone blocker rarely survives and the leftover damage still gets through. Critically, the trample bonus is the recurring portion of the card; it keeps taxing every block the creature draws for as long as the Aura stays attached, while the card draw fires only once. The whole package is built to punish the act of blocking rather than to win a single combat outright, a more aggressive design axis than the three-mana rate suggests. It reads as a clumsy enchantment until you notice it is really a standing tax on defense, paid in damage trampled rather than combats won.
