Whenever Mr. Foxglove attacks, draw cards equal to the number of cards in defending player's hand minus the number of cards in your hand. If you didn't draw cards this way, you may put a creature card from your hand onto the battlefield.
Mr. Foxglove rewards keeping a low hand: attack each turn to refill your grip up to the defending player's hand size, or—when your hand is full—cheat fat creatures into play for free. You build a value engine around drawing, lifegain, and dumping high-impact bodies, grinding opponents out with card advantage and big threats while lifelink keeps you safe.
Built-in card advantage that scales against control/draw-heavy tables
Free-cast creatures when your hand is full, enabling huge mana cheats
Punishes opponents and balances hand sizes to keep Foxglove's draw trigger live.
Add evasion enablers (Whispersilk Cloak, Rogue's Passage) and protection (Heroic Intervention, Lightning Greaves) so Foxglove reliably connects. Lean into the free-cast mode with high-value creatures and reanimation-adjacent bombs, then tighten the mana with duals, fetches, and fast rocks like Mana Crypt and Sol Ring. Top-end can include a compact combo such as Aetherflux Reservoir to convert your lifelink and draw engine into a deterministic kill.
