The rules change to split cards in ELD means that when a card (like Electrodominance) grants casting permissions, it looks at the properties of each half of a split card individually, rather than combining them like it used to. So if Electrodominance is cast for X=2, it should be able to cast each half of Fire/Ice. Currently, it can only cast Fire/Ice if X=4 (the combined CMC).

Steps to reproduce

1. P1: Wish for Fire/Ice and Electrodominance




2. P1: Wish for and cast Abbey Griffin (as a target for Ice)




3. P1: Cast Electrodominance targeting P1 for X = 2.




4. Resolve Electrodominance.

Actual Results

P1 is not given the ability to cast either side of Fire/Ice

Expected Results

P1 can cast either side of Fire/Ice

Notes

The following cards go down similar code paths to Electrodominance and have similar casting restrictions, so I expect them to also be broken and be fixed with the same changes:
Sram's Expertise
Baral's Expertise
Yahenni's Expertise
Rishkar's Expertise
Kari Zev's Expertise
Brain in a Jar

Effects that say "each player discards a card" or "each opponent discards a card" causes adventure cards to gain a context menu allowing the user to choose to discard the creature or the adventure.

Steps to reproduce:

P1: Wish for Beanstalk Giant.
P1: Wish for and play Rotting Rats.
Begin resolving the Rotting Rats triggered ability.
P1: When prompted to discard a card, select Beanstalk Giant.
Actual result:
A context menu appears giving P1 the option to discard either Beanstalk Giant or Fertile Footsteps.

Expected result:
P1 is prompted to confirm their selection.

Notes:

Media attached.
Regardless of which option the user chooses, the card is discarded.
Effects that look at the type of a discarded card will see the type of the side that was chosen (i.e. choosing Beanstalk Giant counts as discarding a creature card, but choosing Fertile Footsteps does not). Some examples include Civilized Scholar, Strongarm Tactics.

Examples of cards with which issue occurs:

Creeping Dread
Liliana of the Veil
Mind Raker
Mindlash Sliver
Nicol Bolas, the Ravager
Rankle, Master of Pranks
Rix Maadi, Dungeon Palace
Serum Raker
Smallpox
Strongarm Tactics

Examples of cards with which issue does not occur:

Borderland Explorer (each player may discard a card)
Syphon Mind (each other player discards a card)

When Exotic orchard is in play and can produce multiple colors of mana, Incubation druid ignores these mana types as mana that the land could produce. Based on the rulings, it should be able to produce mana that any land in play on my side could produce. I was playing in commander and I had a forest and an overgrown tomb as well as exotic orchard. My opponents had lands that could produce white, blue, red and green. My exotic orchard could tap for white, blue, red and green. However when I went to tap the incubation druid, it only produced green and black.

For over a year I've noticed that during drafts, I see a lot of packs in which there's a foil copy of another card in the pack. Obviously this happens occasionally in paper, so there's a chance it's selection bias, but the odds of it happening multiple times in one draft seem like they should be very low.

While it might not have a huge effect on drafting, trust in MTGO ability to randomize properly is critical to players being able to trust the shuffler. I don't want to become a "shuffler truther" but things like this make it far more difficult.

The attached screenshots were all taken from drafts I did over the course of two days.

I have filtered my card library to show only foils that I have between 1-20+ of. It pops up with a card but then says I have 0 of them. Why would it show in my filter if I have 0 of them? Why is it the only card that shows up that I have 0 of?

There are cards that have adventure that I realize it shows 0 of on the 2nd adventure part of the card. But Righteousness and Fling are not adventure cards, why are they showing up as if I should have them in my collection when I filter it but then they are not actually there, it shows (0) of them.

If a player has Syr Konrad, the Grim in play and they then cast a spell such as Heart's Desire (the Adventure part of Lovestruck Beast), then when it goes to the graveyard, Konrad doesn't see it as a creature entering the graveyard from anywhere.

This is incorrect as Konrad can't go back in time and see that it was an Adventure spell that entered. He should just see it as a creature.

Steps to reproduce:
1.Player A casts Syr Konrad, the Grim.
2. Player A then casts Heart's Desire.
3. In response, Player B casts Counterspell targeting the Adventure spell.

ACTUAL RESULTS:
Lovestruck Beast goes to the GY and no trigger occurs

EXPECTED RESULTS:
Syr Konrad sees Lovestruck Beast enter the graveyard and it's ability triggers.
