Pokmon TCG Stellar Miracle (Japanese)
It can win games just by being cast, but has a prohibitive cost and no way to keep it on the battlefield if other players target it
First was this: These cards use the +1/+1 counter as a means to permanently grow something else (and to be fair only Weaponsmith did this out right, Transmogrant kind of hinted at it without directly naming the +1/+1 counterthis would later be fixed in Oracle)
The last way white lends aid to your mana base is by helping you tutor (search your library) for lands (often Plains cards), and adding them to your hand
If there arent many cards in your collection, its worth having a look at the Pokemon TCG Subreddit as people sometimes give away code cards on there
If a player has no cards left to draw at the start of their turn, they lose, regardless of who has more LP
