AI prefers to attack with Stoneforge Mystic/Elvish Piper rather than activating their ability

[MorihiroS]

Describe the bug AI prefers to attack with creatures with activated ability "tap: put card on the battlefield" rather than activating its ability if doesn't have any big creatures on the battlefield:

• [ ] Stoneforge Mystic (even if it has Kaldra Compleat in its hand and activating the ability would deal more damage);
• [ ] Elvish Piper (even if it has big creatures in hands).

To Reproduce Steps to reproduce the behavior:

1. AI casts Stoneforge Mystic and finds Kaldra Compleat
2. Player doesn't have any big creatures on the battlefield, he passes the turn
3. AI attacks with its Stoneforge Mystic

and

1. AI has Elvish Piper without summoning sickness and untapped Forest on the battlefield and Iona, Shield of Emeria in hands
2. Player doesn't have any big creatures on the battlefield
3. AI attacks with its Elvish Piper

Expected behavior AI should activate Stoneforge Mystic's/Elvish Piper's ability as often as possible, priority should be higher

It's just as relevant for Elvish Piper:

@Agetian i think the crux there is that for the Activated Ability, it checks that it should activate them in MainPhase2 ? (maybe it should activate them in MainPhase1 in case the Creature might have Haste?)

And/Or we need a Check for "Should this Creature Attack?", and AI should remember "Wait, I want to Activate an Ability for This In MainPhase2" (we could use some AIMemory for this?)

Except if the Attack would be lethal of course
