Thats a little more than youd pay normally when you look at Deadly Dispute and Fanatical Offering, but this basically draws three cards since you get the land, and it gets all your death triggers rolling
Players need to expend ink from their ink well to play these cards
Heres how my turn three went: Vivi, Bauble, Mox Amber, tap both, add two mana for Vivi, then tap Mox again for Flame of Anor
He's also great with RLS Legacy - Solar Galleon, giving him Evasive when you play him and then making it easier for you to get more characters onto the Legacy, making them all hard to deal with
To maximize the probability of perfect curve-outs, Ive generally mulliganed duplicate ink costs, keeping the best of each drop and bottoming the rest
