This is a powerful card, especially if your hand is empty. It lets you draw seven cards, though it doesn't allow you to play more than one Supporter card before you attack.
For most decks, such a handicap won't be a problem. However, there are some archetypes that will find this restriction annoying.
In any case, this is a fantastic new card that resembles the days of Sycamore and Juniper, which are long-gone from Standard.
