Wee Champion is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Whenever you place a sticker, this creature gets +1/+1 until end of turn. If it's an art sticker, instead put a +1/+1 counter on this creature.

Complete guide

Wee Champion is a small but mighty Minotaur Child Guest that rewards you for your creativity on the battlefield. This red creature turns every sticker you place into a permanent or temporary power boost, making it a growing threat in any Un-set inspired game. Depending on the type of sticker you use, Wee Champion can scale from a temporary attacker to a massive permanent force.

Sticker Powered Growth

The core mechanic of Wee Champion revolves around placing stickers. Every time an effect allows you to place a sticker on a permanent you control, Wee Champion's ability triggers. It doesn't matter if you are placing a name sticker, an ability sticker, or a power/toughness sticker; the child finds inspiration in all of them to gain +1/+1 until the end of the turn.

The Art Sticker Bonus

While regular stickers offer a temporary buff, art stickers provide a permanent upgrade. If the sticker you place is an art sticker, the replacement effect 'instead' changes the buff into a +1/+1 counter. This means Wee Champion can grow significantly larger over the course of multiple turns if you focus on the visual flair of your cards.

Common Mistakes

A common mistake is thinking Wee Champion must be the recipient of the sticker to trigger. This is incorrect; the ability triggers whenever YOU place a sticker on any permanent you control. Additionally, remember that the replacement effect for art stickers only applies to art stickers specifically—other sticker types will only result in the +1/+1 end-of-turn boost.

When to Play Wee Champion

Wee Champion is best played early in a deck designed to utilize the sticker mechanic. Since it only costs one red mana, it can be on the board before you start casting spells that allow you to place stickers. It acts as a payoff card, turning your utility stickers into offensive pressure.

Interaction examples

Early Game Pressure

Ragavan, Nimble Pilferer

You play Wee Champion on turn one. On turn two, you cast Ragavan, Nimble Pilferer. If you use an external effect to place a name sticker on Ragavan, Wee Champion will trigger and become a 2/2 until the end of the turn, allowing for a more aggressive combat phase.

Permanent Scaling

Ornithopter of Paradise

With Wee Champion and Ornithopter of Paradise on the battlefield, you activate an ability to place an art sticker on the Ornithopter to customize it. Because it is an art sticker, Wee Champion's ability triggers, and instead of a temporary boost, you put a permanent +1/+1 counter on Wee Champion.
