How to use this deck:
1. Mana ramp into playing everything possible. If you happen to have 3 mana left over in a turn you can cast Omnath.
2. If you happen to have Omnath out, play enchantments or equipments to make him more OP, then tap all your mana to make him big. Attack and watch people cry.
3. Always attack with a big Omnath before playing other things like more mana ramp or big bombs.
4. You think Omnath is vulnerable to removal? There are cards that let you flash Omnath back to the battlefield, regenerate Omnath, or simply giving Omnath hexproof/shroud/indestructible. Totem armors are also included.
5. Got pesky chump blockers on the enemy's side? Don't worry, there are spells that will be able to give Omnath trample.
6. Need draws? Too bad, I'm still working on that.
