"Tea Gardner is a good early game character for you to put some time into. Getting her deck skill “Holy Guard” is a great backup plan for any deck. “Holy Guard” makes it so you take no battle damage during your next turn after usewhich can be highly useful in some situations.Tea is really only worth leveling for getting her gems and the skills “Holy Guard” and “DuelStandby!”which allows both players to start with an extra card in their hand at the start of the duel."
