Each tin has a unique code on the bottom to identify the packs inside before purchasing
With this piece, Im going to offer some advice on that, starting with perhaps the most popular and intuitive deck theme for new Magic players: tribal decks
The Skarmory ex deck, which was the only wholly new one, was the third most successful at that time, but that's now plummeted to 13th, and Pichu and Magby are the only two Pokemon introduced in the latest expansion to see any successful competitive action
So I've had this Alesha, Who Smiles at DeathAlesha, Who Smiles at Death deck together for a while
It even converts a board wipe into a win condition if the board gets cluttered enough
Just double check this guide for the current price before committing to any purchases
