I think its time Combo made its presence known in Standard, don't you? Exile Triton Tactics onto Elite Arcanist, then tap Zhur-Taa Druid for one damage and one mana to activate the Tactics on Arcanist to untap and repeat for infinite damage! A nice little addition is Illusionist's Bracers + Kiora's Follower
and Volcanic Geyser for infinite mana/damage.
If that isn't enough, there's a way to get infinite mana with Bracers, one Follower, and an Arcanist with Tactics: tap two lands to add 2 to your mana pool, tap the Follower equipped with Bracers to untap them. Tap them again (4 mana in pool), use one floating mana to activate Tactics on Arcanist to untap Arcanist and the Follower, repeat for +1 mana in your pool every time! I don't think anyone has found this combo before, maybe because it is a lot more work than the other two. However, in a deck with both you now have more options to go infinite and hit a Geyser, more options = more lethality.
For protection we have Izzet Charm, Simic Charm, and Swan Song to watch over our combo pieces. Additionally, Izzet charm and Magma Jet can be used to ensure we find what we need, along with all the scry lands.
Just when your opponent thinks he's got you figured out, you can side out Druid, Arcanist, and Tactics for Flesh / Blood
+
Mistcutter Hydra
or Teleportal (has to be overloaded with your infinite mana!!) to kill them from a totally different angle! One that they most likely will never see coming.
This is a rough version, but I love the synergies and the combos, Suggestions are greatly appreciated, lets make this viable in Standard!
