Ratchet, Field Medic (EDH / Commander)

[quote]The object of this deck is to gain life and reanimate Threats into play.

Discard/Mill Engine: These are the most important cards in the deck. Draw cards and discard Threats so that you can cheat them into play. If your opening hand doesn't include one of these or a Tutor, you should consider a mulligan.

Royal Guard: Ratchet can't reanimate anything if he's dead. These cards aim to keep him on the battlefield. As a bonus, Ratchet can reanimate some of these cards without any support.

Threats: Discard these, especially if you don't have the mana to cast them. Cheat them into play later with Ratchet's reanimate ability.

Lifegain Loop: Archangel of Thune, Heliod, Sun-Crowned, Nykthos Paragon, and Cleric Class are among the best cards to combo with Ratchet. When you to gain life, put counters on Ratchet, the next time you attack with him he'll gain you more life, you'll get more counters to put on him, etc. It's a good loop.

Other Lands: Severally lands help you gain life. Note that many of these lands are artifacts too. This enables Inventors' Fair.
