Magicaids on Alternate Win-Cons Kenrith

3 days ago

with Kenrith there is a card that is not a win con but acts like one with him in play it is. but that is up to you i know that you want as many alt-win cons as you can. but a fun idea as well is Tainted Remedy. The best way to set it up is to use ether Training Grounds Heartstone or Biomancer's Familiar. then you need to have Composite Golem ether in the graveyard or in play and you will have infinite mana of every color but black by just reanimate him with kenrith and do it over and over and then with any card with a death trigger that pings for 1 or you give any player five life with tainted remedy out it will kill them by draining 5 life from them and not you. as well ask help with other stuff. overall you if have any question about anything just ask i may not have explained it very well. i love the deck and am staring to put and alt-win con deck together as well +1 from me and keep up the good work love it

Cool deck, +1!


  • Training Grounds / Heartstone to make her activation cost 1 mana, freeing up more mana to draw cards.
  • Ancient Tomb if your mana base can handle it, it's great ramp.
  • Avaricious Dragon seems interesting, because you can draw extra cards, suspend your whole hand, then have nothing to discard.
  • You might want some more ramp in general, seems pretty low, even with her cheating stuff out.

Good luck!

Nylea would benefit a lot from having a Heartstone in play.

pyrostorm96 Thanks! To answer your question, since Cryptolith Rite allows you to tap a creature for one mana, with Heartstone / Biomancer's Familiar out the cost for Pili-Pala 's ability becomes one mana plus untapping it. Basically, you tap Pili-Pala for mana with the Rite, then use that mana to untap it again, thus creating one floating mana, then rinse, wash, and repeat for as long as you want!

dinkyfink on Pashalik Mons Gobbo Combos

nataku Agreed. They do work with other creatures such as Moggcatcher (which I need to purchase and add) Goblin Sharpshooter and Rummaging Goblin . For that they might be worth running at the risk of a dead draw.

Had Heartstone in a one point to reduce Pashalik's cost. However it's symmetrical and only a few creatures benefit.

Smorgaz on Sliver Commander based on PDS: Slivers

Hello WelshGuitarist I might put the Wild Pair back in, I'm just not sure what I should put out for it. Chromatic Lantern is already in. Since I removed most of the slivers with activated abilities, I don't think Heartstone is very useful anymore. Sentinel Sliver is too weak on its own IMO, but I think I have one flying around somewhere, so I might test it out. Hibernation Sliver is probably pretty good in the format. I should really find a place for it. Intruder Alarm is too expensive money wise for the few combos I might be able to do with it. Kindred Discovery would be absolutely amazing in the deck but is also very expensive. If I put in a mana doubler, I would rather use Zendikar Resurgent , because it gives me cards to use the mana on as well. Thank you for the suggestions.
