Reconnaissance is one of my all time favorites. Not only does it allow you to fearlessly attack with everything, but you can still untap your creatures after they deal damage in the end of combat step, effectively also giving all your creatures vigilance (sort of). It's versatile, powerful, and I highly recommend trying it.
In fact sometimes it's necessary to play white and it's exiles and board wipes to even have a chance of winning or something indestructible or hexproof will just ruin things.
Not a bad toolbox green creature to add to your decks after Acidic Slime and Reclamation Sage. It's only upside to those two is dealing more damage to the opponent in combat plus a subtle bonus of being in a beast tribe. Although being an Elf like Reclamation Sage is better.
Only as back up if your opponent plays Shatter on your Chromatic Lantern.
Gustcloak Savior is a bird that also grants this ability.
Keep in mind Onslaught engineered it for the Soldier creature type to cross over with Bird. Keep an eye out for Aven Warhawk or even use Captain of The Watch with enough Bird Soldiers. Look out for the Odyssey block cycle of bird legends. Lieutenant Kirtar, Major Teroh and Commander Eesha.
Currently I toyed with the notion of Lich's Mastery and Skirge Familiar into Gray Merchant of Asphodel into Exsanguinate.
Even just using it to ramp or reanimate or both seems fine.
That artwork too, reminds me of early Suffocation albums. https://www.metal-archives.com/images/6/7/4/674.jpg?1109
Excess extra turn spells
Stasis
Eye of The Storm
Jokulhaups
Commanders - More the deck than the individual card
Narset, Enlightened Master
Animar, Soul of Elements
Best removal from Swords To Plowshares and Path to Exile. In addition to all best board wipes.
Mana rocks for ramp. Angels like Akroma, Angel of Wrath. Zetalpa, Primal Dawn the best Elder Dinosaur. Late game big mana into a Martial Coup, White Sun's Zenith or Decree of Justice.
In fact sometimes it's necessary to play white and it's exiles and board wipes to even have a chance of winning or something indestructible or hexproof will just ruin things.
In all seriousness it's fun to use with a topdeck based strategy with something like Zoologist or Intet, The Dreamer.
