MTG Salvation

I got a playset of Burgeoning and came up with some ideas to use/abuse it. After some playtest, I came up with two different ways to use the card.

The first version is Sultai, with a graveyard recursion sub-theme:



In playtest, this deck almost always win with a large number of big flying tokens, but games where I also get close to lose by selfmilling the entire deck are not rare.

The Temur version has a different approach and tries to abuse broken ways of card drawing, so I can always have lands in hand:



Both decks are really fun to play with, and i feel the Temur version is more straightforward. However, sometimes the Sultai deck seems to lack focus at times, and the Temur version seems a bit greedy. I really want the decks to have the "lands matter" archetype, and win through beating, in a "traditional" way. So guys, are there ways to tighten up both decks? Cards I'm missing here?
Thanks!

First card that always comes to mind when I want to "use/abuse" Burgeoning, is Storm Cauldron. Although it probably won't win you many friends.

If decking becomes a legitimate threat you can always toss in a card like Elixir of Immortality.

Otherwise, the most glaring omission that I'm seeing is card draw. Burgeoning is great, but if you jam it on turn 1 and dump your lands into play by turn 2 then it (and every future copy) immediately loses all of its value. Don't get me wrong, that's still good, but you're not maximizing its potential impact on the game. Decks like these should field some form of mass card draw such as Mystic Remora, Windfall, Wheel of Fortune, Day's Undoing, Whispering Madness, Reforge the Soul, Recurring Insight, etc. to ensure that everyone is cycling into new hands. After all, your opponents won't be able to cast more 1-2 spells from their new grip whereas you'll be able to dump yours.

Don't play Explore. If you're going to field 8-10 Bouncelands stick with Summer Bloom. Blood Sun also works in Red versions of the deck. Your Bouncelands ETBU, tap for 2 mana, and don't bounce another land when you have one of those in play. It also cantrips and hoses opposing spell lands. That's the main thing that it offers over the alternatives; it's never a dead draw since it replaces itself.
