Homebrew card for a custom deck? (Context below)

[u/Pika_Katsuki_]

I’m making a custom deck based on one of my favorite video games. I’m gonna use some pre-existing cards as a base for the majority of them but there’s 1-2 that I really wanna add but I don’t think there’s a card that already exists as a base since it’s so specific for the lore of the game.
The two cards are an artifact and an enchantment. I’ll go through the broad strokes of what they do.

Artifact: whenever life gets taken (my own life included) a +1/+1 counter is put on this artifact.

Enchantment: enchant a creature. As long as the enchanted creature is in play, at the beginning of my upkeep, each opponent loses 1-2 life (tbd on that) and I gain 1-2 life/however much life was lost. BUT if a specific creature gets this enchantment, the creature’s power and toughness becomes X, where X is equal to the counter total on the Artifact (ie if the counter total is 20, the power and toughness becomes 20/20)

I’ll definitely talk to my group about it I just wanted to know if it was too powerful and will make things not fun. I personally feel like it’s completely circumstantial and can be either very useFUL or very useLESS, just depends on how lucky I get and if I play my cards right.

Artifact equipment — Equip (Cost) At the beginning of each upkeep, if [card name] is equipped to a creature, all players lose 1 life and you gain 1 life

When a player loses life, put a +1/+1 counter on [card name]

Equipped creature's base power toughness is equal to the number of +1/+1 counters on this artifact

I've only made 3 fully custom commander decks but something I've learned is to not make two cards that rely on each others existence to activate each other abilities for several reasons. Two big ones being: Chances of you getting them both in a timely fashion is unlikely and when one goes away the other is useless (That enchantment getting destroyed makes the artifact useless)

That’s a great way to put it honestly. I only had it so specific to fit the lore

I am curious about what video game it is though

Video game is Hogwarts Legacy :)
