Biomancer's Familiar Discussion

Cinestra on Golden Control

I very much still am active on this primer! I really appreciate any kind of question and I'm happy to answer any of them!

In my opinion, you shouldn't really heavily depend on Tasigur's activated ability for value. The reason being is that Tasigur's activated ability is extremely costly, like you point out. Even if he had an activated ability like Thrasios or Kenrith, 4 mana for just one card hardly is a good deal in cEDH. He's a great sink for dumping excess mana, but utilizing him as your primary source of card advantage is going to be very rough because of how mana intensive he is. Instead, you should really be looking to develop another card advantage engine first (Sylvan Library / Dark Confidant / Oakhame Adversary / Rhystic Study / Mystic Remora / Necropotence / etc). These kinds of tools can really help you generate the value you're looking for. And then once you have your card advantage and ramp set up, you can funnel excess mana into Tasigur activations.

In my opinion, the mark of having six mana up for Tasigur activation AND a counterspell is a sweet spot for me. Perhaps in your pods you might have like a lot grindier games where that doesn't cut it though. If you're looking to squeeze more value out of Tasigur activations or hold up more mana for counterspells, I would highly suggest trying out Training Grounds or Biomancer's Familiar. I recently cut Training Grounds in my most recent update, but I've honestly been really thinking about going back on it lately. I think particularly Training Grounds would be an amazing addition to help you with this exact dilemma you're describing.

Not sure if I entirely answered your question, but hope it helps! Please feel free to shoot another comment if you have any follow-up questions or whatnot. Thanks!

if you are going to play this deck, you probably should be playing Biomancer's Familiar, Mox Diamond, Dack Fayden, as well as removing kiki, pod, felidar, and other bad wincons that don't allow you to win at instant speed. adding another land would also be good, as well as playing pyroblast.

The_Munchkin on Deck does not contain a lapdance *ding* Sliver EDH

CrimsonWings3689, I have taken the Diffusion Sliver in and out of my deck. I've realized that my current meta focuses a lot more on mass removal and hardly any targeted removal so I just haven't found it that useful. If and when the meta begins to shift I will definitely be slotting it back in and may look into picking up the Unsettled Mariner as well.

As for Biomancer's Familiar and Seedborn Muse they are both very good cards and I'm sure they would be useful in this deck but I do want to keep it on somewhat of a theme, so I only include slivers (changelings are fine too because they still technically are a sliver). While I want the deck to be powerful that is one constraint I have placed on it.

Thanks for the suggestions though I'll take a look at your deck for some inspiration.

As someone who also has a Sliver Overlord deck, I'm very surprised to see you not running Unsettled Mariner and Diffusion Sliver for the innate protection they provide to your pieces. Often times your opponents' just won't be able to pay for the tax while you build your combo.

Biomancer's Familiar (2nd copy of Training Grounds) and Seedborn Muse have made their way into my list as the only non-sliver pieces because of the value they provide.

Meeknomore on Infinite Combos in EDH - Experiment Kraj Budget

This may not work well as it doesn't contribute itself to Kraj, but Biomancer's Familiar would help lower the activation costs of a lot of your creatures, notably Gilder Bairn, Pili-Pala, and Arcanis the Omnipotent.

In my +1/+1 counter deck I run an infinite pumpability combo with Biomancer's Familiar and Gilder Bairn alongside either Rishkar, Peema Renegade or Jiang Yanggu

CaptSillva on Thrasios

Burnished Hart seems like an odd choice for a deck with green in it. Especially since there are still decent options like Sakura-Tribe Elder.

You could also consider Training Grounds and/or Biomancer's Familiar to go along with Thrasios. You also have Cancel on this list, but it should likely be Force of Negation, Disallow, or Whirlwind Denial.

The win con also seems to be Lab Maniac, but there are other cards that have this effect such as Jace, Wielder of Mysteries and Thassa's Oracle. Both could be worth considering.

Magicaids on Alternate Win-Cons Kenrith

4 weeks 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
