Aqua Sniper, the penquin soldier of Duel Masters. This is card is dangerous as it is, because no one wants to have to resummon to creatures and wait for their summoning sickness to fade; by that time you could be shieldless. But as they say two heads are better than one. Well i say 4 heads are the best. If you are able to acquire 4 Aqua Snipers, and plan on playing blue, then you have a potential deadly combo. Using Nautre mana acceleration cards that i mentioned in a previous tip, you could potentially get out your aqua sniper's early game. With 2 aqua snipers in hand, you hand systematically "bounce" your oppenents creatures back to their hands. If done right this can lock your oppenents into a summoning craze, as long as you remember to return one of your snipers to your hand to continue the bounce fest. Enjoy this and use it well.
