Thanks for the write up - I love the deck.
I've played the deck online on and off for a couple of years.
I love your main deck canonists - it makes a lot of sense in this meta.
In my current build I play more of the sol lands + 3 chromatic lantern. The card has really overperformed. It gets you to 4 and completely fixes your mana.
I also play a myr battlesphere as my tinker target; I've found it better at buying time against mentor and shops decks.
