Why This Matters You're probably wondering why this matters, and the truth is that if you are playing split cards "fairly" (i.e., just casting them normally from your hand), you won't even notice this rules change
The current Standard format has quite a fantastic array of sets available to make decks with right now (Sword and Shield, Rebel Clash, Darkness Ablaze, Champions Path, Vivid Voltage, Battle Styles, Chilling Reign, Evolving Skies, Fusion Strike)
Theres not a lack of support for damage equal to toughness cards - Ancient Lumberknot
And getting a near mint condition of this card isnt going to cost you nearly as much as the other Charizards on this list, but could run you nearly $800
