Activated abilities of creatures cost less to activate. This effect can't reduce the amount of mana an ability costs to activate to less than one mana.

Lostsorrow on Unicorny Power

Magikarpet I really like Workhorse a lot. I would most likely be picking one up to replace the Myr Battlesphere. I like having the Brood Monitor combo so to have an extra version of that would seem like a good idea to me. Heartstone although very awesome, I am not quite sure what I would cut for it. The deck is quite tight right now and it would require over the top cards to replace others. The only slot I may consider sneaking it into would be to replace Kitchen Finks as it's really dependent on having a sac outlet and Good-Fortune Unicorn out. The only other card slot I could consider would be Wild Pair. Great suggestions :)

I'm also working on an Emiel deck right now! Came here looking for more inspiration. I highly recommend working Heartstone into the deck if you can since it reduces Emiel's blink cost. It's another way to allow Brood Monitor to generate infinite mana. Even if you don't have an infinite combo on the board, if you wanted to blink 3 things on your turn, you would need 9 mana. With Heartstone in play you only need 6.

Also Workhorse goes infinite with Emiel in a similar way to Brood Monitor, though I don't know if it would be worth it to add another 6-drop. It is a horse though, which is kind of like a unicorn.

Omniscience_is_life on High-cost abilities

thank you all so much for your advice. Let me make clear a few things that I clearly didn't, previously (and that's my mistake): I'm trying to build a Zirda deck (noncommander, so don't worry about identity) with other cards like Training Grounds, Heartstone, Biomancer's Familiar, etc. to try to get a bunch of abilities with mana costs similar to Planar Bridge's for free/near free. Not just looking for generically good Zirda cards, although it is truly nice to know them. Thanks again sorry for being confusing ;)

Superman53 on If Kobolds Could Kill (Explosive, Turn 1 Win)

I had a 5 color Sliver deck that used a similar method to combo out... the good ol' Recycle and Aluren combo. Add in a couple Heartstones and a Sliver Queen. Earthcraft made for infinite creatures too! It took a little bit to set up, ensuring your ramp could get both the green enchantments on the board early enough. Basically, Alluren made all Slivers into 0 CMC creatures (like the Kobolds), during Tempest/Stronghold.

Heartstone? Might also want to swap a couple of the taplands for basics, could probably stand to get a few more mountains in there.

So I get not wanting to run Heartstone for fear of opponents using it to greater effect than you, but I didn't mean running Zirda, the Dawnwaker as companion (duh that would be stupid) you can run it in the 99 to great effect and it is a sliver! You run Amoeboid Changeling, so everyone is a sliver :D

In all seriousness, running Zirda, the Dawnwaker in the 99 as redundancy to Training Grounds does make some sense, even if it is a filthy non-sliver. It's just another great combo-enabler.

"Question: why no Heartstone or Zirda, the Dawnwaker?"

Zhugo12, thanks for asking that - I've already got an answer pre-baked in my head regarding Heartstone, and that's an easy one to answer - because if you read the card closely, it awards the cost reduction of abilities to all creatures on the board. Let me be clear - in cEDH you do not help your opponents under any circumstances - doing so is akin to either forfeiting or playing kingmaker. Before you even think "Oh, but you can use it with..." No. I'm not going to have a card in this deck that is essentially dead until I get Sliver Queen and Basal Sliver on the board.

As for Zirda...the short answer is that I would essentially have to cripple my deck in order to fit Zirda in as a companion. There's a sizable number of permanents in the deck that do not have activated abilities, namely Mana Echoes, Training Grounds, Mirri's Guile, Mystic Remora, Sentinel Sliver, Sliver Overlord (the list goes on, you get the idea) would have to be removed or substituted for just one card that provides a nominal boon at best. What's amusing is that even the other card that you mentioned Heartstone can't even be included alongside Zirda. Heartstone is a static ability (it's always on), not an activated one (which requires some sort of payment to activate - , pay , etc)

Additionally, Zirda is a filthy non-sliver. Yeah. I said it. I don't like non-slivers in my Sliver Tribal deck. I can't even tutor for it using the Commander's first ability. I'd have to waste a tutor to fetching it as opposed to getting a Mana Dork or an actual Wincon. Zirda doesn't contribute in anyway to the cohesive strategy that Slivers bring - not awarding any special abilities tha
