Most underrated current evergreen keyword on creatures?

Trample. A 15/15 will only do so much if it can get distracted by a 0/1 bird.

Seriously, trample has been making the difference between chump-blocks and game-overs since day 0, yet the only mention it got in this thread so-far was in a post about how nasty it is to combine first strike with deathtouch. As far as underrated goes, you got your winner.

And on that note, yes, deathtouch & first strike do form a pretty spiffy synergy, but did you ever wonder why there's not a single creature out there that combines trample and deathtouch? Well, it turns out that "any amount of damage is lethal" is a bit too ludicrous if you pair it with "any damage done to blockers beyond lethal damage carries over to defending player/planeswalker."

Really, I think deathtouch. Oh, you have a 15/15? Here, let me kill it with a 1/1.

Underrated, not overpowered. Silly.

My choice would be trample. People fear a vanilla 6/6 for 6 as much as a 6/6 for 6 with trample. Even though only one of those can be chump blocked.

Hmm perhaps shouldn't have used the  number 6. Oh well, I think I am going there anyway.

I like First Strike a lot. Having played Narset, it allows a lot of things to go your way that otherwise wouldn't.

Obviously Trample and Hexproof are good, but I don't think they are underrated at all.
