New Keywords from Battlebond and Guilds of Ravnica

I'm not sure if there's an update I might have missed in the last 6 months since we moved to the new forum, but I've created keywords for the Battlebond and Guilds of Ravnica sets.
How are we distributing updated keywords these days?


Partner with {name}
When {if contains(card.super_type, match: "Creature") then "this creature" else if contains(card.super_type, match: "Land") then "this land" else if contains(card.super_type, match: "Artifact") then "this artifact" else if contains(card.super_type, match: "Enchantment") then "this enchantment" else if contains(card.super_type, match: "Planeswalker") then card.sub_type else "this sorcery"} enters the battlefield, target player may put {param1} into their hand from their library, then shuffle.
I wasn't sure how to get the card to recognize that the Partner card would be a legend, in the event that we have a future design like a squire summoning his liege, but I figure it would be easy enough to copy and paste the reminder text.

Assist
Another player can pay up to [{substring(card.casting_cost, end:1)}] of this spell's cost.
If anybody can provide some guidance to fix the character spacing on Assist so that the colorless mana symbol can fit on the top line with the keyword, I would be very grateful.

Mentor
Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.
Undergrowth
(change keyword type to pseudo)
Jump-Start
You may cast this card from your graveyard by discarding a card in addition to paying its other costs. Then exile this card.
Slam dunk, just here for completion's sake.

Surveil
Look at the top {
if param1.value==1 then "card of your library. You may put that card into your graveyard."
else "{english_number(param1)} cards of your library. Put any number of them into your graveyard and the rest on top of your library in any order."
}
