That sounds about right. The only thing I would say about 4 is that those spells need to fit your game plan. I didn't use threat because some decks don't really have those early. 3 land, arbor elf, farseek, and a [card:Okay, so first guideline:
Mana Source - Your opening 7 should have:I threw number 4 out there because it seemed common sense, but what would you think is a good value for X? 50%?
- 1. No less than 10% of the total number of mana sources.
2. No more than 15-20% of the total number of mana sources.
3. 5-10% minimum of each color of mana represented.
4. The correct amount/color mana to cast X% of the spells in your opening hand.
1r5hxlu5]Thragtusk[/card] sounds legit even though Thrag is the only real threat. Likewise for my deck, x2 plains, mountain, x2 boros charm, x2 oblivion ring is probably a straight mull even though I can play 100% of the cards in my hand.
