Had 2 corpsejack manaces in play, triggred a +1/ +1 evolve. Each corpsejack menace has an effetc to double +1/ +1 counters but only 2 counters were added not 4.
Previous Ruling:
17/11/2017 If you control two Corpsejack Menaces, the number of +1/+1 counters put on a creature is four times the original number. Three Corpsejack Menaces multiplies the original number by eight, and so on.

Words of Waste isn't triggering when I pay for 1 on my upkeep and not drawing for turn.

Chainer, Nightmare Adept does not allow you to cast creatures using its ability on your opponent's turn when Vedalken Orrery is in play.

Steps to recreate: Put Chainer, Nightmare Adept and Vedalken Orrery into play. During an opponent's turn, activated Chainer's ability, discard a card, then attempt to play a creature from your graveyard.

Her plus one let me cast the card it exiled with its plus one for the whole game.

My trade function is blocked, please help me to unblock, thaks!

I just opened some treasure chests that had a Hatching Plans and an Bostinate Baloth among them. The Hatching Plans was blue (as it should be) but had the Image of the Obstinaate Baloth. The Image is/was correct in the inventory afterwards.

Cards like cloudshift do not properly return commanders to the battlefield. It is very annoying and constantly ruins games for me. Please fix it.

I had used phyrexian metamorph to copy my opponent's commander (atraxa praetors' voice) I then Mutated it using chittering harvester choosing over, I twice attempted to attack my opponent the creature removed itself from combat and advanced through my combat step.

boil didn't do anything when my opponent played it in a game of modern. I think it was likely caused because I had a leyline of sanctity in play.

My Luminous broodmoth regenerated my mutated creature when it should not have. I had a porcuparrot, prickly marmoset, and dreamtail haron that were all mutated (porcuparrot on top). When he used blood curdle to kill the creature, they all came back with flying counters (even dreamtail haron)

returned to the battlefield with the landfall ability.

Swallow Whole is not working.

In the game, it came back to my turn, so everything is untapped and I have creatures. I went to cast Swallow Whole and it wouldn't do anything. I had the mana and the creature for the additional cast, but it was like clicking on empty space. No acknowledgement of even trying to cast a spell, like pay W or pick target.

I can't draw with Diviner's Lockbox. Steps:
1. Have Elsha of the Infinite on the board and see the top of my library (it's a plains)
2. Activate Diviner's Lockbox, and name plains.
3. Actual: Diviner's Lockbox resolves, stays on the field and I don't draw cards.
4. Expected: Diviner's Lockbox is sacrificed as the card I named was the same as the one on top of my library and I draw three cards.

Happened again with a mountain, could be just basic lands, but haven't got to test other cards with Elsha.
