#deathtouch
Honourable mentions to Scry, Lifelink and Double Strike.
1] Flying - Isperia, the Inscrutable
No one loves flying like baby Isperia, who really wants you to assemble a toolbox of flyers for all situations. Use bounce flyers to make sure Isperia always hits (Mist Raven, Aven Surveyor), then flyers can do almost anything - land? Pilgrim’s Eye. Removal? Hypnotic Siren. Card Draw? Sphinx of Lost Truths. Creature Protection? Dust Elemental. Counter Spell? Silumgar Sorcerer.
Then use all the Flying tribal - Sprite Noble, Warden of Evos Isle, Thunderclap Wyvern, and Gravitational Shift.
Special Tech - Windreader Sphinx, draws a card whenever a creature with flying attacks. Note that this isn’t just your own creatures! Draw all the cards!
2] Deathtouch - Marath, Will of the Wild
There are many ways to build a deathtouch deck, and most of them revolve around pingers aka Tims aka creatures that tap to deal one damage to a target creature. Giving them deathouch can turn your Tims into machine guns. But I wanted a slightly different route and went for the Naya-coloured Marath.
When combined with Nightshade Peddler, Bow of Nylea or an equipment like Gorgon Flail, Marath can use his counters to mow down the opposition. Wasteland Viper is good here, as both a defensive creature or an offensive trick to boost Marath with deathtouch.
Build up a board of deathtouchers, and either give them the ability to ping (Power of Fire, Thornbite Staff) or make your opponent attack their creatures into yours (Bullwhip). Deathtouch also works really well with First Strike and Trample, so suit up with Chariot of Victory or the Sword of Vengeance.
Special Tech - Odric, Lunarch Marshal. Any white deck build around keywords would love the ability to share them all. Have a deathoucher and a trampler to give Marath all the keywords an Elemental could dream of.
3] Prowess - Shu Yun, the Silent Tempest
While it could almost be a Jeskai theme deck, Prowess has slowly begun to spread throughout Magic, allowing for a greater range of possibilities. Use the best of the Prowess (or prowess-like) creatures - Abbot of Keral Keep, Jhessian Thief, Monastery Mentor, Niblis of Frost, Soulblade Djinn.
Then power them up with cheap cantrips or spells that can be cast more than once - Distortion strike and Centre Soul have rebound, Mystic Speculation has buyback, Crown of Flames can be bounced back to hand for a red mana.
Special Tech - Scroll of the Masters. Each spell you cast puts an extra counter on the scroll, to boost whichever creature can get through. With Shu Yun’s ability to grant double strike, you can deal a huge amount of damage.
4] Indestructible - Nin, the Pain Artist
Nin loves to torture people for information, and it turns out there are no better victims than indestructible creatures, who just keep giving you more and more. The darksteel creatures, especially Darksteel Myr, are excellent creatures to shoot over and over, or Nin can shoot herself with Darksteel Plate. Slobad can grant Indestructible to any artifact at the cost of a disposable one, and Soul of New Phyrexia is protection for your whole team.
Follow that up with Red wraths that can’t hurt your team, like Blasphemous Act, and Chain Reaction. To clear the way for indestructible beaters like Colossus of Akros or Ulamog.
Special Tech - Stuffy Doll. Shoot the poor doll in the face, draw that many cards, AND shoot an opponent for that much damage. Good times.
5] Protection - Teysa, Envoy of Ghosts
Protection is one of the most powerful keywords you can have, working both offensively (preventing blocking) and defensively (from damage and targeting). But how to spread it around? Before there was Odric, there was Concerted Effort, that among other keywords will also share Protection abilities.
So which protection abilities do we want? Protection from Creatures comes from Teysa herself, or Beloved Chaplain. Pro CMC 3 or more comes from Mistmeadow Skulk. Elite Inquisitor, Akroma, and Baneslayer Angel each come with a bevy of keywords, as well as some important Protections.
Then make a bunch of tokens and get in with your pro-everything army.
Special Tech - Cairn Wanderer. If your Concerted Effort has been exiled, and your creatures killed, Cairn Wanderer can do a decent impression by sharing all the keywords of your dead creatures. In a pinch it gets the job done.
If you had to build an EDH deck around an evergreen keyword, which would you choose?
