Muddle the Mixture 2: Augstralian Kangafrog

Up: Not a fan of how the landfall proc only checks for one type of line as that doesn't feel very organic. Other than that, interesting but mediocre take. 

Hand of Dromoka
Creature - Hound Knight
You may remove four +1/+1 counters from creatures you control rather than pay CARDNAME's mana cost if you control a Plains.
Flash
When CARDNAME enters the battlefield, target player sacrifices a tapped creature.
3/3

Next: Jerrard of the Closed Fist and Dungrove Elder

Up: Elegant muddle of the given cards - with some added stuff that makes it balanced yet playable. I like the Hound Knight subtype

Elder of Jerrard
Creature - Elemental
~'s power is equal to the number of Mountains you control and ~'s toughness is equal to the number of Forests you control.
*/*

Next: Staff of the Ages and Spirit Shackle

Up: Ran some numbers in my head. For reference, I think the fact that you need to pay not to get kerfuffled every turn balances this out nicely.
for a condition-free discard 1, for a condition-free discard 2, etc. Seems okay. 


Shield of Empires
Artifact
, : The next time a source of your choice would deal damage to you this turn, prevent that damage. Then, it deals damage equal to the damage prevented this way to target creature or planeswalker if you control artifacts named Staff of Empires and Throne of Empires.

Next: Burning-Fist Minotaur and Ruthless Instincts

Up: Nice rare to be afraid of. I think the ability would be ok at two mana since you can do it only once each turn. Would fit nicely into Amonkhet.

A Tale of Reality
Enchantment
Whenever you cast a green spell, choose target opponent. You may have you and that opponent create a 2/2 green Wold creature token.
Whenever you cast a blue spell, choose target creature you control and target creature you don’t control. You may return both creature to their owner’s hand.

Next: Windreaver + Myojin of Infinite Rage. Oh wow. Have fun.

Up: First mode of the ability is basically an infinite combo in of itself. Then again, Omnipotence exists to make infinites happen. Maybe this is fine. 

Ironroot Elves  
Creature - Elf Warrior  
: Add . 
: Monstrosity 3. (If this isn't monstrous, put three +1/+1 counters on it and it becomes monstrous.) 
0/2

Next: Skarrgan Skybreaker and Untamed Hunger

Up: Good Muddle. I even like this one better than the original Skybreaker.

Worm Charge
Sorcery
Target player sacrifices a legendary land, then sacrifices a land. Creatures you control get +1/+0 for each land in that player’s graveyard.

Next: Spirit Token... uh, no wait... Cyclops of Eternal Fury + Luminous Bonds

Up: You certainly combined the cards mechanically, but in the process you lost one major part of Bestow: the bestowed creature doesn't grant any abilities or restrictions that it itself doesn't have when unattached.  I like the idea, though - and I especially like the addition of a color to just the bestow cost.  8/10

Rabid Sliver
Creature - Sliver 
Slivers you control have ": Choose target
creature you don't control. That creature gets
-1/-1 until end of turn, then this creature
fights that creature."
2/2

Next: Unfulfilled Desires and Treasonous Ogre.

Up: Interesting and fun, but it's missing a bit of the feel of the Ogre - more like Stygg or Pain Magnification. 6/10

Pretty clunky but:

Oppressive Mantle
Enchantment - Aura
Enchant equipment.
Convoke
Activated abilities of enchanted equipment cost  more to activate.
Enchanted equipment has "Equipped creature cannot attack or block unless its controller pays

"Hard to draw a blade in these ceremonial robes. Still, we have to stand - err, kneel - on ceremony." - Vimes, Guardsman

Next: Gaea's Herald + Whirlwind

Up: A very interesting boardwipe. The two effects make a weird combination, but it's a fun bonus. Looks very anti-blue without directly referring the color. I'ts definitely something green could do.

Lightbug Hive
Creature - INsect
Whenever Lightbug Hive is dealt damage, you gain that much life.
Pay 50 life: Create fifty 1/1 green Insect creature tokens.
Morph
6/6

Next: Blessed Reversal + Island. Hm. You can take Ichorid as second card if you want.

Up: foco, you are supposed to give feedback to the post above!
Your card is a nice and funny muddle of the two cards. It probably makes you crunch some numbers in your head before deciding what to pay for X. Sacrificing Goblins to pump your other Goblins feels like a very Goblin-y thing to do.
There is just one problem: Tecnically the card doesn't remember what you paid for X when it enters the battlefield, so either you can ssacrifice any number of Goblins or X will allways be 0. (I'm not sure which one. For that reason, Quarantine Field uses counters.) One way to make it work would be "When ~ enters the battlefield, pay and sacrifice X Goblins, if you do, ..." That way you also dodge weird removal interactions where someone removes a Goblin or two after you paid for .

Galea, Wind’s Whisper
Legendary Creature - Angel
Flying, hexproof
Prevent all combat damage that would be dealt to Galea, Wind’s Whisper.
At the beginning of each end step, if seven or more damage has been prevented to Galea this turn, draw seven cards.
7/7

Next: Stampeding Wildebeests + Giant Strength

UP: A 5/5 trampler for 5 is good, and a 7/7 hasty trampler for 5 is great, specially in limited. Still, I think bounce effectes are more of a UG thing rather than a RG's, but still, pretty good card after all.

Also, thanks for the feedback! <3
Here's my card, and the next two are Darkmor Sorceress and Fling. ¡Good luck!

kazerima : Pretty good, simple design. We've seen this design before on Cragganwick Cremator and Heart-Piercer Manticore. That said, this is an uncommon at best.

Lillia Orith, Mechanist
Legendary Creature-- Human Artificer
Whenever a nontoken artifact you control is put into a graveyard from the battlefield, you may pay . If you do, scry X, where X is that artifact's converted mana cost. You may reveal an artifact card from among them and put it onto the battlefield.
"I will find you, little brother. No matter how long it takes. No matter how far I must go."
2/3

Next: Aura Gnarlid + Voice of All
