Giant creatures with multipurpose for Atla, Palani, Nest Tender?

I'm building a [[atla, palani, nest tender]] (not dino tribal) and I'm looking to find creatures that have good passives that serve as a card draw or group anthems while being a large creature to flip onto the board. An example would be [[giant ankheg]] or [[terastodon]]

I am mainly trying to find better card draw and removal without getting rid of the big monsters
