I had This Town Ain't Big Enough, an instant which would return my blocker to my hand. I had 2 mana (one blue) available for the reduced cost for casting on my own creature but didn't get the chance.

Myrel and Kutzil are cards that don't allow you to cast spells during ypur opponent's turn.

After blockers declared, I had enough land to cast an instant that would save my blocking creature and destroy the attacker, instead the game went right into damage. This has happened now 3 times today and has failed to allow me to cast an instant before the damage phase.

same thing happened to me multiple times. Game is broken... hard to believe any of the winners truly won? Guess it depends on your definition

So, I have some instants that I do NOT want to use almost ever, in my hand, but the stupid game at every single time tries to get me to use them, but when I want to use an instant that I DO WANT TO USE, it just skips to damage directly!! Like that black card, forgot what it is called, that gives -1/-1 to an enemy creature. I had two and with my blocking creature, I could have killed his main creature and won the **** game, instead it skipped right to damage phase. This sucks donkey balls!

happened to me just now causing loss of game. What is the compensation for this?

multiple games trying to sacrifice my blocking creature after blockers declared during Damage phase using something like Tend the Pests or Deadly Dispute, damage is dealt during phase and I'm not able to cast any instants

being able to cast instants during the Damage phase after declaring blockers

no work around, basic part of the game not functioning properly and has cost me a win on multiple games, very frustrating

Ive lost many games because of this

Still affects me. Happend to me multiple times on Android and Mac

I'm having the same problem. I have an instant that pumps up a blocker and the MTGA app won't allow me to play it. It is the Tactical Advantage in the White Deck, +2/+2 to target blocker I control.

Same. I declared blockers and it went straight to damage without any opportunity to use Skirk Prospector so that lifelink on opponent's creature wouldn't trigger. Instead, opponent gained 10 life... thanks Arena.

Couldn't respond to declare blockers. Was going to sacrifice my Muxus to prevent Obliterator getting dealt damage. Was never given priority and had to sac all my permanents, losing me the game.

Unable to cast Light of Hope after declaring blockers. 3 available mana, basically nothing on the table, definitely not cards which would prevent it like Teferi. I lost the game and money because it was a part of Standard Metagame Challenge.

This is now getting really annoying. Last couple of games I could have won the game if i could only cast the instants. Are punishing red decks?? This has not only happened with my white red deck but others. It is quite pronounced with this deck.

Same issue experienced here. Lost the game because of it. Very frustrating.

Had the same problem. I had a few instants in hand and many free lands to tap, selected my blocker, confirmed my blocker choice. The damage was dealt instantly, and i couldn't cast any spells (wanted to give my creature +7 +7 and cast fling). In the same match earlier i was able to give my creature +7+7 with the instant i don't know the english name (costs 1 white mana) after declaring blockers. My creature died and i got mad.

So random ...

Yeah, infuriate and shock not allowing me to cast in combat frequently

Yep--lost a game because I swung out and didn't have the opportunity to cast infuriate on my heroic creature in Theros draft. Nothing on board had protection, and there was obviously no Teferi. I had way more than enough Mana up. Lost on the backswing.

Same, just lost a game because game would not let me cast an instant to give all my attackers +2/+2 for lethal after blockers were declared. Opponent was able to kill me next turn. I had more than enough mana to play the instant, and opponent had no cards on board that would prevent me from casting instants.
