Interesting mechanical space with ripple.
Would cards likely be paired, like Surging Protectors to Surging Might or might there be another green creature with Ripple whose name may also be Surging Might but not named Surging Protectors?

Random order or any order for the cards sent to the bottom?

There is no theoretical limit. In practice this has the partner-problem: Each card added to the group increases the combinations and likely power level.

Ripple was designed very much for the set it was in: Coldsnap was a unique draft environment for three boosters from the same small set. In consequence the mechanic becomes weaker for larger Constructed decks or in case you combine it with another set.

This card and related cards are created with that in mind.

If you have a classical/outdated three-set block, I could imagine grouping three cards together with a shared name and inherent ripple.

Sorrow asked: "Random order or any order for the cards sent to the bottom?"

From the comp. rules:

"702.60a. Ripple is a triggered ability that functions only while the card with ripple is on the stack. "Ripple N" means "When you cast this spell, you may reveal the top N cards of your library, or, if there are fewer than N cards in your library, you may reveal all the cards in your library. If you reveal cards from your library this way, you may cast any of those cards with the same name as this spell without paying their mana costs, then put all revealed cards not cast this way on the bottom of your library in any order."
