Besides, nobody resents an extra card until you drop the sphinx

I think that this will make her a little more balanced but still very powerful The only small thing I have with Kolaghan is that it has deathtouch as a 4/3 hasty flier I don't think it all have many chances to utlize deathtouch why not make super aggressive and instead give it flying and haste and "Whenever Kolaghan attacks deal 2 (how many you feel is right I'd personally say not more than 3 and even that a lot) to target creature or planeswalkers (this is not a may ability, as his other effect hits you as well might as make him shock you if there's no other targets) For Silumgar really I'd take off a -1/-1 counter and make them enter with 2 or maybe only 1 of them instead of three as thats a bit harsh seeing as there many other spells that let you take shit from graveyards without such a heavy downside (yes ik it a ETB and that can Abused but i feel with that many counters it will only be adbused for the mill effect), and more for ONLY for flavor and not for practical use (though there is some practical use for it) and that's making the creature you bring back zombies since the sultai were necromancers first and foremost

That means absurd early plays
Avenger of Zendikar: Ending games for land decks since its release, Avenger of Zendikar is still a premiere end-game threat for these decks
Aboleth Spawn copying the trigger from Eternal Witness, Solemn Simulacrum, Avenger of Zendikar, Sun Titan, and friggin Dockside Extortionist is going to be amazing
Offensively Elesh Norn is super weak on her own but oppressive should you have any other dorks in play
