This is a very interesting ally card. It's level is equal to the roll of 2d4 (averaging +5), and can be maximized to a +8 using Rigged Dice (22/MI) (however, the average gain of 3 levels is hardly worth using the card). However, it has two other features that can make it very useful.

First off, it can be played into any round of battle, even when you are not involved, which makes this a wonderful support card for theme tournaments like team partner games, or just when you want to influence other player's battles. This can be very useful, but can be done by other cards, like Foulwing (76/UD), so isn't that special. However, any time during a battle, this ally can blink (return) to its owner's hand. This can be incredibly useful, especially if it is in play first, and then the opponent plays a card that allows instant victory.

Since the Blink Dog was in play first, it can activate its power and get out of the battle before certain death. This also works well when the ally if going to be destroyed by the enemy anyway (however, the Dog can only activate this way when the card is play). Once the counter-effect time is done, the Dog can be killed by cards in play, and once that destruction is declaired, the blink cannot be used as a counter effect.

This card can show up in many fun decks, but not most tournament decks, since bonuses higher than the maximum +8 can be found, many with better powers that help win, not just recover from loss. However, this is definitely a very fun card to play with.
