[3] EDH - Tuned: Power lvl 5-6
6: Decks With A Plan
Deckshave a definite strategy in mind, or multiple that synergize well to enable a solid game plan. Spell choices are more focused, but with mixed levels of efficiency. Lands entering untapped are prioritized. Battlecruiser decks are uncommon. Most decks contain at least one hard wincon, usually a combo. Decks have a modest budget.
5: Upgraded Precons
Decks probably have a good broad strategy in mind; most are somewhat generalist, often employing a wide array of "goodstuff" cards, like draw spells, board wipes, etc., to supplement their primary goal. Mana bases and card choices are better, but often still inefficient, due to budget or prioritizing personal favorites over strategic choices.
