Speaking of Explosive Vegetation, Advocate interacts pretty favorably with that card as well, jumping you from four to six mana on turn 4 to upgrade it into mid-game form
Reach (This creature can block creatures with flying.) At the beginning of combat on your turn, put X +1/+1 counters on another target creature you control, where X is Halana and Alena's power

The color pair is atypical of what you expect from a dragon deck, and the +1 isnt much of a deterrent from attacks
Justice Strike can only outright kill creatures with a power equal to or greater than its toughness, of where there are plenty in Guilds of Ravnica
I am also running Maze of Ith, and I wish that I had a free copy of Island of Wak-Wak
