Forest Enchantress - I will go with suggesting a different wording also, though the way I interpret the card is Forest Enchantress has hexproof when not in the Combat Phase
Dire Ancient - A bit overpowered, especially with not having much land destruction around. At the very least, I would suggest making it give only give colorless mana unless you control a Tower, maybe entering tapped. And instead of being indestructible with a tower, just shuffle it back into the library. Just to make a turn 1 Dire ancient not be completely amazing.
Satyr Trickster - Interesting ability. Not sure how powerful it would be.
Zeus, Lord of Olympia - Creatures that can ping for even 1 are pretty highly costed anyways, this ability is crazy strong, and the ability to ping 1 damage for each spell is really powerful. And the 3 power puts him out of Shock range.

Satyr Hellcaller - The regenerate cost on this one is kind of high. Are there even that many Regenerate costs in general that expensive?
Templar Assassin - I feel that this one should be a higher rarity. And it's activated ability feels more like a White ability.
