Thanks for your reply! I will address your suggestions by the steps you listed:
Step 1: I know
winter orb and
static orb are the usual win condition cards for this commander but I don't find it fun to play with and neither do my friends that I usually play against. I'm definitely open to other suggestions and I will try looking for other options as well.
Step 2: I will probably keep
Tropical Island but will be taking off
Calciform Pools for on of the land cards you suggested. Also,
Bloom Tender is, or should be, in the deck already. I will take a look at the artifacts that you suggested.
Step 3: This deck is to play with friends on Cockatrice so I don't have a budget. However, my friends and I try to stay away from really broken cards to keep it more fair since we aren't worried about card costs.
I would love any additional help and any other suggestions to help make a more original Derevi EDH deck. Thanks in advance for your help and guidance. I look forward to your reply. I am still pretty new to making my own decks so feel free to recommend any fun and/or interesting ideas that can be added to this deck.
