I want to talk Mechaz0r. I really don’t like this unit - but I won’t be ranting about balance changes here (there’s a topic with a pair of interesting mechs changes ideas), but rather about the lack of basic logic.
What is Mechaz0r? It’s a giant mech, combined from smaller ones, conveniently called Helm, Wings, Cannon, Sword and Chassis (see Mechaz0r lineup official art for reference). That’s actually cool. I loved Voltron and those giant Transformer robots from later seasons back in the 80s and 90s TV series.
Yet summoning Mechaz0r defies all logic. First of all, progress is accumulated by any component mech. Three Helms and two Wings allow you to summon Mechaz0r - but it should be some three-headed, four-winged monstrosity without torso, legs or weapons. Yuck. True Mechaz0r should require all five different components. And they should be present on-board at the same time AND be removed after Mechaz0r is summoned (like Obliterate removes creep and Deepfire Devourer kills surrounding units to gain boost). How can destroyed mechs become functioning parts of a combined robot?
Yes, it will shift the balance of mech decks tremendously (possibly beyond any possible fixes), but current situation is just stupid, IMO. But maybe it’ll stop players from creating mech-only decks. It is possible to build a mech deck with more diversity - I’ve played against such players, and it was more fun than all the mech-centered battles combined.
There is a simpler solution. And it won’t affect balance at all. Just reimagine Mechaz0r as an avenger from deep space who is summoned by the beacon signal, which is boosted by each mech summon. I think it’ll be acceptable at the logical level, at least.
