The 5-sentence Commander game plan I win by: (combat damage, combo, commander damage, drain, lock, alt win, etc.) I get there by: (tokens, value engine, graveyard loop, spellslinger, stax, big mana, etc.) My commanders job is: (engine, payoff, tutor, glue, finisher, or distraction) My backup plan is: (what you do when the main thing gets hated out) My biggest problem is: (fast decks, wipes, grave hate, counterspells, artifacts, etc.) If you cant fill this in, do not buy more cards
