1. i used the U/B ability from Lochmere Serpent to get him back into my Hand
2. 1 turn later enemy played macabre mockery and targeted my Lochmere Serpent
3. lochmere was in my hand not on my graveyard

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.

A player plays time twister with an underworld dreams and spiteful visions on the field. Duel caster mage was then cast to copy the time twister. The triggers from underworld dreams and spiteful visions go on the stack. However the game breaks and causes an infinite loop of the game replay instead of resolving the triggers

Soul Exchange did not grant +2/+2 counters.
1. Soul Exchange was cast exiling Basal Thrull targeting Mindstab Thrull.
2. Mindstab Thrull was brought back to the battlefield.
3. Actual: No +2/+2 counter was placed onto Mindstab Thrull, resulting in a 2/2.
4. Expected: Mindstab Thrull should have a +2/+2 counter on it resulting in a 4/4 Mindstab Thrull.

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.

platinum angel is on the field so i cant lose the game, but immortal coil keeps trying to endlessly trigger, preventing any player from doing anything, timer won't go down for either player, after a few min of softlock the game just starts a replay

game screenshot attached ( with match number)

Savage Swipe may or may not give lethal damage as a +2/+2 counter?

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

happened in my match number # 228995695 game number #719448950

I cannot save my address info on the game, therefore it is not possible to purchase the account upgrade kit since everytime I click on Checkout pops up the address info

1.I cast Dovin's Veto on his Narset, Parter of Veils.
2.My opponent countered my Dovin's Veto with Negate.
3.Actual:It gets countered by Negate.
4.Expected:It is uncounterable.

1) Cast Pillar of Flame targeting Bloodghast.

2) Expected Bloodghast to go to exile.

3) Opponent fetched a land with Wooded Foothills and Bloodghast
returned to the battlefield with the landfall ability.

4) Expected it to die and be exiled from Pillar of Flame.

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.

Was playing a strong deck in my premier draft today and not once but twice lost a game due to Valdok mutate ability not casting the selected card (ram through).

A player is able to use a card's suspend effect (i.e. Ancestral Vision) after using their Teferi's +1 Planeswalker ability.

EDIT: Your report page is bugged and doesn't give me the option to pick the category game play report bug. See Screenshot.

I also wanted to report on the card. Offspring's revenge on a possible bug.

Opponent has offspring's Revenge with a lot of creatures in their graveyard.

Like a drakuseth dragon. I used a Elspeth nightmare to eventually empty their graveyard. The opponent is still able to access their grave yard exile to use their offspring's Revenge. Is this bugged? They didn't target any card from their graveyard. There's nothing there.

Today I tried return to play mtgo, but then I had to create a new account using the same e-mail I used before in my mtgo account, the when I logged in all my cards had gone ! Please, someone help me.
