Really, though, it doesn't matter what dual lands you play (as long as they often come into play untapped)the deck could just use a few more of them to add consistency
Dragon Ravine also provides an option to add Dragunity Corsesca from deck to hand
Armorcraft Judge , for example, is an Elf Artificer that will draw a card for each allied creature that has a +1/+1 counter on it, and Immaculate Magistrate can tap to put many +1/+1 counters on another Elf creature
4 loyalty Player 2 - During his or her upkeep, Player 1 uses Teferi, Master of Time to use its first ability to +1 and Loot
The other thing that Serrated Arrows had going for it was that it killed creatures via -1/-1 counters
Its very fitting for Morph, who can alter his shape into basically anything
