Aside from attacking hard, you can gain plenty of small creature tokens to finish your aggressive assault if Anax is removed
Dont forget that you can activate the ability on your opponents turn too, allowing you to go from zero cards to seven (including your draw for the turn) in just one turn cycle
Not only is the cards Secret Illustration Rare variant the most expensive card in the set, Terapagos ex also looks to be a disruptive force in the metagame
The former is good in the Devotion lists where you play less Ramunap Ruins and more Mountains, while I just love the latter as it helps mitigate flood and can easily trigger prowess and spectacle when its not busy killing your opponents one-drops
For example, if you control three creatures and two Starlight Spectaculars, each Spectacular will give one creature +0/+0, another +1/+1 and the third +2/+2
Secondly, most repeated card draw effects are board state related and can not currently be modeled (e.g., SkullclampSkullclamp, Mentor of the MeekMentor of the Meek or Soul of the HarvestSoul of the Harvest)
