This deck is built around the fun combo of Fathom Mage and Lorescale Coatl.
Lorescale Coatl and Horizon Chimera both proc on card draws here, which is a pretty cool mechanic.
There are two ways this is accomplished beyond the standard card draw at the start of your turn.
1) Brainstorm, for1 blue you can proc "Whenever you draw a card" three times, and as an instant! I like it. It could really mean the difference if you were baiting someone else to attack/defend.
2) Fathom Mage is the big one. Whenever a counter is placed on her you get to draw a card. There are several ways THIS is accomplished as well, which I'll go into below.
Counters:
This deck was made to play with counters, it's just a neat way to play the game.
1) Increasing Savagery is a big drop of 5 counters, which is huge for this deck. Drop 5 onto fathom mage and that's a 5 card draw and 5 counters for it's cost, if you have Lorescale Coatl out that's 5 more counters. On top of that, you can cast it again from your graveyard for ten. CHeck please?
2) Vorel of the HUll Clase: It would be silly NOT to have him in here. DOuble counters on target creature? Don't mind if I do.
There is Primordial Hydra and Predator OOze as well, but those are in here not because they contribute a lot to the combo but because they fit so well within it. Easy to drop. and bothcan get out of hand if left unchecked.
