It counted the first three creatures as the green pips in the casting cost and then required me to pay three additional mana to cast chord. Convoke, delve, and improvise all supersede the 3 cost requirement and so shouldn't have prohibited me from casting the chord of calling in this instance.

Played karn, exiled a card with a counter on it, it was bounced, replayed it, later tried to get a counter card but i couldn't select anything

Balance just put the creatures from my hand into the graveyard in a random order

Sometimes I can cast Hour of Revelation only WWW even opponent and I aren't control ten or more nonland permanent.

"Spell pierce" did not fire targeting "fact or fiction.'

archbound mouser died and the modular ability triggered wich it says : ( when archbound mouser is put in to a graveyard from the battlefield, you MAY put its +1+1 counter on targe artifact creature)
The opponent owned 2 artifact creatures and i had none but i couldn't stop the trigger from happenning and the game was forcing me to place the counter on opponent creatures basically.

Make The Ozolith a creature with a 1/1 counter on it, then make The Ozolith target itself with it's own triggered ability.

I had The Ozolith under my control with a 1/1 counter on it. It was made into a 1/1 creature by Karn, the Great Creator. During my turn, I moved to combat and selected The Ozolith as the target for it's own triggered ability to move counters - expected behaivour is no counters are added or removed, but the single 1/1 counter on The Ozolith was removed.

glimpse of tomorrow doesn't show all the cards like the card says. It puts permanents into play, but it does not show you which other cards go to the bottom of the deck.

When I use a sweltering suns, and I have two zendikon winds on the opponent's lands, my enchantments do not return to my hand, but remain in the graveyard

My opponent played my Koth of the Hammer off of his Fallen Shinobi. He wanted to +1 it, but didn't have any mountains so he untapped one of mine. This gave me open mana to cast an Incinerate, but the game would not let me tap the mountain for mana. As it was, it didn't effect the game in a major way so I didn't create a reimbursement request, but I wanted to report the issue. I assume it's a bug. I have a screen capture if you need it, but it won't let me upload here (it's a .jpg).

In game 1, I cast Eureka. After going back and forth putting out multiple permanents, I chose to stop. After I stopped, my opponent was allowed to put out an additional permanent. That extra permanent resulted in a loss for myself. In game 2, I cast Eureka again. I chose to put out 1 permanent. Then my opponent put out a permanent. I then chose to not put out any more permanents. My opponent was then able to somehow put out another permanent though they should not have been able to since I declined putting out any more permanents.

In response to a Living End in the stack, I resolved a Dress Down. Then my Thing in the Ice entered the battlefield from the graveyard with four ice counters as the Living end resolved (which should have had zero counters because of the Dress Down).

Casted Solitude on Evoke cost to exile Eidolon of my opp, targeted the creature but the eidolon didn't got exiled.

play teferi time raveler, minus, attempt to target Springleaf drum and fail

Hello, I tried to cast Bloodthirsty Adversary and use the ability to pay multiple times. The app did not recognize the proper colored mana requirements so I had to hit "cancel" as it was my only option. Instead of letting me re-tap, the program did not let me use the ability at all.

I played Jace, and wanted to bounce my opponents creature, but instead my own creature got bounced

when my creature was killed my rancor enchantment never returned to my hand instead it stayed in my graveyard
