Some other tap engines to consider:

Paradise Mantle - taps Kalamax by ramping. so it's never an empty tap.

Opposition - taps Kalamax and allows you tap something else down in response.

Rhystic Deluge - cheap card that taps Kalamax for , and may also be useful to tap down and tax opponents with unused mana. Some utility.

Everyone has different feelings about Howling Mine; that's why I mentioned it with a caveat. It can definitely speed up a game. I like your design here. Very clever!

Lurking Predators is another card to consider that can cheat dragons in just by letting your opponents play Magic.

I would add Plumb the Forbidden first. Instant speed, and it costs 2 less to cast. I play both, but if could only add one, it'd be Plumb.

Temple Bell might be a group hug draw source you'd be interested in. Howling Mine is alright, but everyone benefits from it before you do, so consider that before adding it.

I've got a Kathril deck myself. I play him by being selective about the creatures that go to the graveyard (with a few mill effects as well), and I like to use sac outlets to get creatures I've cast into the graveyard. There are some good budget options out there that are quite useful, like Fanatical Devotion and Martyr's Cause to name a few. Spells that reap rewards for sacrifice, like Plumb the Forbidden, Village Rites, and Reprocess are very useful for killing off keyword creatures and refilling the hand. I also run Survival of the Fittest, which is great if money isn't an option, along with Evolutionary Leap.

A newer creature that is worth looking into is Oriq Loremage. Does exactly what you want this deck to do.

Good luck moving forward with this deck. I enjoy playing with Kathril.

Pir, Imaginative Rascal is great human that does what you want with counters. I know you don't want to run too many non-human creatures, but Beast Whisperer would be worth it for the card draw, and Rishkar, Peema Renegade would help you ramp like crazy. Rootborn Defenses is another good protection option.

I originally had more two-drop rocks, but went away from them to go with more land ramp. I'm actually considering dropping some more of the artifacts I have, but have not convinced myself to do so yet. Urza's Incubator and Herald's Horn are good, but once I get Gishath out, they tend to not be quite as useful with Gishath doing all the work to get dinos out. I've been keeping them around because I know there will be times when my Commander won't be an option.

My mana base is pretty good, so I won't be adding Terramorphic or Evolving Wilds. If I didn't have the mana base I have already available, I would probably run them.

Regal Behemoth is out of budge, as is The Great Henge. I own a copy, but it's in another deck for now. The Tarrasque's fight ability could be useful, but it probably won't ever have Ward 10 in this deck. I'm on the fence about it. Rampaging Brontodon is easy beats, for sure.

You're right about the small buff that Rhythm gives, but in a deck with big creatures like this, I just don't worry about the buff as much. If it were a deck of elves or goblins, then maybe. But with a bunch of 4+ power creatures, I'd rather fill that spot with something that is going to offer more function, like another protection card or a draw spell.

I love seeing an old card like Sacrifice show up! Great suggestion!

Engineered Plague is another one to consider.

Thanks for looking, Monomanamaniac. I like your budget suggestions, and a few of your not-so-budget suggestions. Etali is slated to go into the deck...I just need to buy or find another copy in my collection. I'd like to add Wayward Swordtooth, but that may take some time. Runic Armasaur isn't that far out of budget, though, and I think I will add it, too.

I'd considered Rhythm of the Wild as an upgrade to Fires of Yavimaya, which I had in the deck, but I removed it, mainly because if the deck is running right, creatures are entering the battlefield with Gishath's ability, and haste doesn't do much good then. Next time I go upgrading, I'm getting those cards!

I forget about Necrologia all the time. Very underrated card.

I would consider some different card draw options. Simple ones like Night's Whisper, Read the Bones, and Ambition's Cost are effective. I really like a card like Plumb the Forbidden, especially in response to a board wipe. Arguel's Blood Fast  ^Flip is an underplayed card in my opinion. It's not as good as Greed, but it might be better than Phyrexian Arena.

If I were looking for cuts, I'd be curious about the performance you've gotten out of Skeletal Scrying, Soul Foundry, and Well of Lost Dreams. The well seems like it's really good in any lifegain deck, but to get a big bang out of it, you've got to always keep a lot of mana open, and be gaining life. Perhaps you've made it work well for you, though. Let me know your thoughts on these.

Hehe, thrulls are thrilling...

Link didn't work. But I would run Vilis as the Commander. More direct payoff for life loss.

To help your ramp, you could go heavy on one-mana dorks, including Birds of Paradise and Elvish Mystic, and then some two-mana land ramp spells, like Nature's Lore and Three Visits.

I like your approach here. I think if it were me, I'd lean more into an Enchantress approach to Voltron. In fact, that may be my next deck!

The umbras, like Bear Umbra and Snake Umbra offer nice protection. And there are quite a few.

It looks like you could run a few more Enchantresses for some more consistent card drawing.

I like this take on Atraxa!
