Four Suit Transfers:
Many people play four suit transfers, where, over a 1NT opening, you bid 2♠ to transfer to ♣'s and 2NT to transfer to ♦. This is great.
I like to play Puppet Stayman as well. Doesn't "everyone" open 1NT with a 5 card major? You should! Since Puppet Stayman is 3♣ over 1NT, there is no obvious way to bid a natural ♣ bid. For ♦ you "could" use 3♦, but I prefer to show that as 5-5 in the minors, slam interest.
Does anyone combine Puppet Stayman and 4 suit transfers? Maybe 2♣, then 3♣? If so, what do you do with 4 of a major and clubs?
