Oh, it's not like the environment hasn't any landfall in it. In fact, my current plan for 600 will have 6 cards with actual landfall trggers in blue, plus 
Barrin, Tolarian Archmage, 
Glasspool Mimic and 
Trade Routes as well as 
Adventuring Gear in colorless. I just wanted to make sure, that the next blue landfall enabler didn't necessarily need all the green stuff to have a realistic chance of seeing main deck play. 
 
I was very close to just taking Sea Drake, but I don't like that it becomes removal roulette sometimes. Maybe I should be cubing the Tsunami, but I figured my blue decks want counterspells more often than undercosted beaters.

You know what? I had one open spot left in blue and this is going to be my last new card. It might not be super powerful, but it might hit the sweet spot between 

 landfall and 

 spells, as well as fitting nicely into the mono color/devotion theme I'm having.
 
The final reason I am sticking with Deprive for now however, is my latest draft. My girlfriend build a sweet 

 fish-like tempo deck, playing all the 
Savannah Lions and 
Sunhome Stalwarts, backed up with bounce and counter magic. Deprive did nice work in that deck from turn 3 or 4 on, where she could add another cheap aggressive creature to the board or play a 
Pacifism while keeping the counter backup.
