Going all-in on lifegain is seen as a beginner trap because life points dont do anything other than empower your other cards

Terastodon, Woodfall Primus, and Primeval Titan are probably the best cards for the "big green creature" role, but Simic Sky Swallower and Broodmate Dragon can serve the role as well, although they require greater deck manipulation to be able to hard cast should you draw either of them before finding your Natural Order

Obviously lots of commanders want this, like Toski, Bearer of Secrets and Yuriko, the Tigers Shadow

Is it uninkable

Some creatures can remove first strike from another creature, either through blocking or an activated ability
