Heres what I like to do when tuning my mana curve: First, I set all the lands aside so that all the cards left are creatures and spells
This fantastic card ensures consistency on an incredible level, making it a natural fit into any deck featuring Charizard ex, and really, any deck that can benefit from the free card each turn
Japanese cards carry lower counterfeit risk because the complex Japanese text is harder to replicate, domestic distribution is tightly controlled, and the print quality (embossing, foil, cardstock) is expensive to reproduce
Also, turn 1 land, Artificers Assistant into turn 2 mana rock (of which I know you likely run many) or T2 commander gives you an immediate advantage to manipulate your draw for turn 3
You can just crack open the box and play
