Replaced Defense Grid with Leyline of Lifeforce .

All completed.

It might be worth considering Kiki-Jiki, Mirror Breaker + Zealous Conscripts for an alternative win condition.

Completed.

Add Seeker of Skybreak and Splinter Twin to maximize combo ability.

Completed.

I do like Voltron decks. Looks like a fun one, and kudos for having a competitive deck that you can tone down with a commander switch to have a bit more fun wit.

Probably should replace the slow lands with Gruul Guildgate and Highland Weald .

Have you considered Triumph of the Hordes as another route for eliminating someone?

In fact, I was seriously looking at it today. However, unlike most of the other kill-conditions, this ability is not repeatable outside of combo'ing with another card like Past in Flames .

For kill-conditions, I think repeatability is pretty key.

I don't disagree with having some re-usability, but if your down to one opponent left, then it can be pretty useful.

Which card would you slot out for it?

Godo, Bandit Warlord seems to only work for Samurai, unless he is in there just as an equipment tutor, which seems like a bit much to search up an equipment. Perhaps he could go?

Godo is in the deck for the Godo, Bandit Warlord + Helm of the Host combo.

Replace Highland Weald with Kazandu Refuge .

Completed.

Might be good to add Battered Golem and Guttural Response .

Completed by removing the more greedy ramp cards.

Quicksilver Amulet and Belbe's Portal are a form of flash.

Grafted Exoskeleton is the only recent piece that was a big bummer to lose.

Added it back.

Perhaps replace Argentum Armor and Steel Hellkite with Spine of Ish Sah and Scour from Existence in the sideboard.

Completed.

I wonder if Ranger's Path would be better than Explosive Vegetation ?

Stonewood Invocation looks like it can save Atarka from removal as well as get her kill-ready.
