I love all these cards too.
Zaku is a beast! But... I have managed to beat it a couple of times with the new Lir Deepswimmer card. It's an awesome counter.
I use it often as i find joy in my opponent fuming in front of their Pc due to many misses on it in battles....
haha, same here....
i haven't come across an opponent using deepswimmer to counter my zaku yet but i definitely know the summoner is a threat to zaku..am prepared for it lol//thanks for your feedback
