Mulligans
Goal: Get Eonar, the Life-Binder on board and copy her a bunch to make ancients, fully heal and draw your deck. Usually your use here mana refill when you play her and then use Cover Artist /Shattered Reflections to get more. If this doesn’t win Audio Amplifier can allow you to play Death Beetle and copy it with Shattered Reflections to charge for the win (Shattered Reflections is a very good card if you couldn’t tell).
The new cards are very good here. Frost Lotus Seedling is a tutor for all your important cards, Shattered Reflections gives even more ways to duplicte your important cards and in a deck all about getting to 10 mana more ramp in Crystal Cluster is welcome.
Nightshade Bud is your other titan tutor, Funnel Cake helps empty your hand to draw more cards and the rest is your standard ramp druid cards. I don’t use Thadius because I personally don’t enjoy him and creature based ramp is avoided to allow your tutors to be more consistent.
