Me too. They are easily expendable, and easily abusable, but the whole point of the deck is to overrun, a strategy that is often foiled by mass destruction decks like my Pestilence-based deck. And the Boros-based Cleansing Beam.
The Golgari are also pretty good in my opinion, but they have more weightage on coming back again and again and again. Regeners are annoying, which I have experienced first-hand as a player and as the victim. -evil laugh-
Boros is the traditional fast and mass-effect deck, so sue them. They abuse speed in the form of low mana cost and first-strike and double-strike, and with enough mana, Oldrun commando is a very annoying enemy.
that's all I know, and I'm trying to get a Golgari deck so that I have a cause for which to steal my friend's uber-Golgari card, the Sisters of Stone Death.
And the second legendary creature for Selesnya is the Chorus of the Conclave, and for Boros, Razia, Boros Archangel.
