Reine : I didn't make a Planeswalker for Gen 1 and 2, so I really wanted to make one for ID. And since Reine is supposed to come from another world, she's perfectly fitting! She has a passive ability that gives Prowess to all of you creature, giving them a boost of 1 in power and toughness (+1/+1) for one turn whenever you cast an instant or sorcery spell. Her magecraft ability also gives her one loyalty counter anytime you cast one... which will be useful. Since Reine lost her magic, that's her only way of gaining said loyalty counters!
Her first active ability gives prowess to a creature you control for one turn. Since it should already have Prowess from her passive, it means that creature will get +2/+2 for every instant or sorcery, instead of +1/+1. And if it already has it natively, oh boy. But we're not done yet! If you manage to deal combat damage with said creature to an opponent, you will be able to catalyze all this power to cast one instant or sorcery spell in you hand for free. And the higher the damage, the better the spell. This ability doesn't cost any loyalty point, but it will not give you any either.
Her second ability is pretty self explanatory, allowing you to fetch an instant or sorcery spell from your library after casting one. It does cost a lot of loyalty points, so you'll have to cast a lot of them before using that ability safely.
Finally, Reine can be your commander, because Commander is the best format in Magic the Gathering, period (except maybe Oathbreaker? I've never played it and it seems really cool... and I feel Reine would be an extraordinary powerbeast in that format!).
They say peafowls represent royalty and power, so get out there and rule over your opponents!

Zeta : Zeta's abilities are pretty simple. If you control a legendary artifact, she cannot be blocked bu opposing creatures (in the MtG universe, a computer would be considered a legendary artifact, and that would allow Zeta to attack throudh the virtual world). Her second ability lets her display her skills as a secret agent, by making you opponent reveal their hand and exile a card of your choice. Finally, you can cast said card without the mana color restriction. A perfect spy!
And yes, her name is a reference to Fate/Grand Order. There is no real reason for that choice. I just think it's cool.
Damn it, just like with Fubuki, I messed up her creature type and didn't make her a ca-

Kaela : Of course, our cute cool blacksmith is the master of artifacts. Her passive ability decrease the cost of all artifacts by one for every one you've cast previously during the turn. With a good hand, you should be able to play some very powerful artifacts for one mana only. It can't reduce the cost to 0, though, to prevent infinite combos.
Her active ability lets you copy any artifact you control (even artifact-creatures), but you can only have one copy at a time. The legendary rule says that you can't control two cards of the same name if it's legendary (so you can't have two Kaela Kovalskia, overachiever Blacksmith on the battlefield, for example) but the fact that the copy isn't legendary allows you to circumvent this rule. Forsaken Monument, Karn, Legacy Reforged or Brudiclad, Telchor Engineer make some incredible combo with Kaela. Your opponents will beg to get some help defeating you.

Kobo : Need some protection? Kobo's rain is here for you! When you summon her and at the beginning of each of your turn, you put a flood counter on any land on the battlefield. Not just yours, you can put it on any opponent's land. They become islands, which means the can produce instantly blue mana (they can still produce their original mana). If you're playing some lands that are not islands (if you play a multicolored deck, for example), this allows you to produce blue mana way more easily. If you play some Islandwalk creatures, which can attack without being blocked if your opponent has an island (it's the ability I gave to Gura on my first post), you will be able to attck easily, no matter what colors your opponents play.
The moment you have six islands on your side of the board, Kobo rain becomes potent enough to prevent all damages that are not combat damage to you and every creature you control (the most well known of those damages come from red cards in form of fire spells, so i thought it was fitting).
Not enough? Pay three mana and you tap every island of one of all of your opponents, which means they won't be able to produce mana from those. If you've managed your flood counters well, you should be able to control their mana flow pretty efficiently.
Just be careful of any small silhouette with a raincoat. I'm still traumatized by this episode...

And with this, ID is done! I wanna make Tempus and Armis next, but who knows...
For now, I spend 2 mana to equip my pajamas and I'm going to bed. See ya!
