Would love ways to run/write automated/custom FOR() and WHILE() loops. This could be first manually implemented and the onus of the player to use this. Setting up FOR() and WHILE() loops for their combos. The only required automation: the client should be able to show you have these pieces in play, would you like to use any of these applicable loops. (Storm like spells would also need to be included in this, especially when they have ‘target’ in their text box.)

The other needed automation: Grouping triggers + Group resolution.

Imagine if I had Vorinclex Monstrous Raider in play and wanted to target it 49 times with instances of +1/+1 counters.

Imagine instead of targeting just one creature, I wanted to spread out N counters over C creatures. When C<N then I should be able to evenly distribute these counters (than having to confirm. Remainder triggers can be prompted or auto distributed.).

Ideally when triggers suddenly stack up >10, try to group these triggers. If opponent is not holding full control and they try to pass through your triggers (or they are prompted to let you pass through your triggers more efficiently). Then let this grouping resolve. The client can show the opponent what is grouped; the opponent can confirm to pass these N triggers.
