Hi Arena.

Hopefully a pretty simple one, and I think for some triggers you may have already implemented this - but, for any trigger that's potentially self-harmful, could you please make the card/trigger apply an automatic stop - I think it would make sense to have it as a blanket "all the time" scenario just in case a player could draw into a stifle effect (or if the stifle effect may not be obvious to Arena, like Sundial Of The Infinite), but otherwise, at least if they have something like Stifle or Consign To Memory in hand (ie. something that can target the ability).

Examples of the triggers are things like Chance For Glory, Pact Of Negation, Demonic Pact, Alchemist's Gambit etc. When you're playing these cards alongside stifle effects you do typically get used to applying manual stops or full control yourself - mainly because you can't afford not to when Arena's trying its best to kill you - but it'd be a nice ease-of-play improvement if Arena just stopped and gave you a chance to react, rather than killing you despite having the card and mana to save yourself.

Cheers!
