Suggestions about new cards!

[Seiya]

To be fair, Silence or Cloak can be worked into most rainbow decks without too much difficulty.

Yet, those cards are useful only when you 've got more than 2.
That is for example, if you lack of a Protect/Enchant Artifact and you are playing your pulveryzer, your bonewall, permafrost or Phase/Dim shield.

Ok, Tea is Good (it feels so weird to write that as a name)
If Zanzarino was to follow your suggestion and make new rushing cards, that would get a lot of use, they would have to be better than the current cards. So he might make cards like:

ScaryGirl  . 6 attack, 2 health unupped, 7/3 upped.

Dragon egg  0/5, immortal. 1 , turns into a random dragon (upped and unupped depend on egg).

These would be imporvements over the current rushing cards (Frog/Mummy ect and Graboid/Lycans). People would start using these, and using less of the other 'rush' cards. Rush decks in general would be stronger, so we would see more rush decks in all forms.
Then, when it comes to make more new cards, Zanz would once again need to top these. Maybe he'd go another route:

Stomach  0/4. Turn  into  , can be used multiple times per turn.
Sunlight. Sacrifice a photon to create  15 

These would possibly replace cards like Rustler and Immolation.
Of course, all of this is exxagerated, but the fact is, that more rush cards would have to be better to get much use, and then rush cards would get stronger, more rush decks would be played, and more general 'uughh' ness.

I dont think his point was to make better rush cards, I think the point was to make non rush cards more useful
