You named your Water Serpent Construct Sir Isaac Newton? Fine. I will name my sword "Apple".And that is a question I've been mulling over. If a mage summons a wall of stone, cam I just phase through it because it's magic? It's all very peculiar.I think you're right there, it makes sense at least.

No no, I mean you're still at the mercy of physics.

That is why I am asking the question too. Lets take the example of the water dragon. In itself, it is, as you said, an physical element being control by magic. So that is fine, nothing really happens. But lets say that the dragon claws a Guardian. The physics of the Guardian being hit still takes place, but the construct came into contact WITH the guardian which is immune to magic... So would part of the claws fall to the ground like normal water as the magic can't be sustained?I know it sounds really idiotic, but I have to ask xD

I would venture to say no. The example brand gave was that a Guardian would take a fireball to the face no problem, but a forest fire started by that fireball would still kill them.
