Oops! Ummm, challenge...

Create a rune card that prevents sacrifice.

Ispita Mirtyu

Legendary Creature-Demon Naga Vampire.

Mythic Rare

All opponents reveal their hands. Until the end of your turn, you may cast spells from their hands without paying their mana cost and their spell's owners lose life equal to their mana value. ~ gets X +1/+1 counters equal to the amount of life lost this way.

If ~ dies, exile her instead. Then create an Artifact Urn token with "This artifact can't be copied." and ", sacrifice this urn: Return ~ from exile to the battlefield."

Create a spell that would be a color break, but very expensive to cast. It cannot have any alternative casting costs.

Plown's Pathmaker

Creature- Dryad

Uncommon

Whenever ~ attacks, target land becomes a basic land type of your choice until end of turn

1/3

Create an aura, equipment, instant, sorcery or planeswalker that gives one or more creatures a land walk of the controller's choice. If you choose planeswalker the ability must be static.

You posted this roughly at the same time most Friday Night Magic events are finishing up. On a weekend where American Gridiron football at every level is determining playoffs one way or another, Moana 2 is in its second week out in theaters and during the Christmas season. If you intend to post again on your own thread to call attention to it, the least you can do is wait another day or two and give everyone another chance to get to it before you go making changes to the deck(s) anyway.

In your Numot deck, while the majority of your cards will only cost one mana less, only 7 of them will fully benefit from Grand Arbiter Augustin IV's 1st two static abilities. So it comes down to whether one mana off and one more for your opponents is worth a four mana card. If it doesn't, then you have the excuse you need to slide in Elsha of the Infinite. Though personally, I'd consider just rebuilding the whole deck with Elsha as my Commander.

As for the choice between Primal Command and Shared Summons, without knowing which decks you are considering, put Primal Command in decks in need of graveyard interaction and/or control and put Shared Summons in decks where you need specific creature cards to carry out a combo.

-Create a card that can shuffle all creatures on the battlefield into their libraries. It must be an Instant or have Flash.

DemonDragonJ, If you really want a sacrifice-based board wipe, I'd recommend Killing Wave. While Vona's Hunger does work for both the short and long game, it won't kill all the creatures. On the other hand with Killing Wave, you can sacrifice all your creatures except for Thraximundar(just eat the lifeloss) and maybe Tergrid, God of Fright  ^Flip, and hold the advantage on the battlefield. Happy Hunting!

I concur with griffstick. You already have so many ways to cause sacrifice your opponents are not going to have enough creatures on the battlefield for the alternate casting cost to benefit your commander. Unless yer playing against go-wide token decks; however, even then it's not going to make enough of a difference without evasion so you can win with Commander damage.

Since you have the Huatli, Sun's Heart/Tree of Redemption combo, have you considered any combination of Felidar Guardian, Angel of Destiny and Test of Endurance? It's always good to have an Alt-Win card in your deck in the event you can't defeat your opponents through combat. I hope this helps. Happy Hunting!

George Herman Ruth, The Babe

Legendary Creature- Human Athlete

Mythic Rare

: ~ deals 1 damage to any target. If this ability causes three or more damage in a turn, you may transform it.

Sacrifice a food token: Untap ~. Target player receives a treasure token.

Babe Ruth, Sultan of Swat

Legendary Creature- Human Athlete

Mythic Rare

Whenever a spell or ability targets ~, you may tap it. If you do, redirect that spell to any target and it's controller receives damage equal to ~ power.

Sacrifice a food token: ~ gets +1/-1 until end of turn.

2/2

So no, there is no mistake here. The general idea is you either cast Babe Ruth, Sultan of Swat from the outset or you cast George Herman Ruth, The Babe and you recount his story as a Major League Ballplayer from his start as a pitcher to the hitter we all know and love today. The food tokens acknowledge his voracious appetite and drinking abilities. The red acknowledges his short temper and party lifestyle while the white acknowledges his generosity towards the poor.
