Sol Ring

+2: Create a 1/1 green Elf Druid creature token with "T: Add G." −2: Destroy target artifact or enchantment. −6: Draw a card for each green creature you control. Freyalise, Llanowar's Fury can be your commander.

Search your library for a creature card, reveal it, then shuffle and put the card on top.

Untap all permanents you control during each other player's untap step.

T: Add one mana of any color in your commander's color identity.

When this creature enters, destroy all artifacts and enchantments. Put a +1/+1 counter on this creature for each permanent destroyed this way.

You don't lose unspent green mana as steps and phases end. Omnath gets +1/+1 for each unspent green mana you have.

At the beginning of your draw step, you may draw two additional cards. If you do, choose two cards in your hand drawn this turn. For each of those cards, pay 4 life or put the card on top of your library.
