This is a smart way of teaching the game, as often when all cards are on the table, or in one's hand, players can get confused looking ahead at them, seeing different abilities or rules they have yet to encounter
There is no rule text stating that these activations don't stack
This blue, red, and white deck excels at producing tons of artifacts, generating a bunch of energy, and then controlling the board until youre able to secure the win
Its also not going to be covering the forgettable cards that are only really good in Limited or as additions to very budget or niche decks, as were more interested in what cards are good to collect and build with in the future, too
If you do, return this creature from your graveyard to your hand
Keep an eye on this
