Gyftrot is a strong Taunt monster, on par with Greater Dog. It is slightly weaker though, with 3 less HP, but is also 2G cheaper and has the ability to make the owner draw a card upon death. Good for the Integrity and Bravery decks in particular, however useful all-round.
Be careful that its ability can also end up with you having to lose cards because of a full hand, so it's not recommended to have this placed down while having 6 or more cards in your hand. This is especially the case in the late-game, where it can be killed more easily.
