If you love having options and aren't scared of a complicated deck, then Jump Scare is an extremely solid precon choice
There are so many fun ways you can use this, but it is also a great resource to have in your classroom for when students have a bit of downtime.
In other words, as long as Regidrago has 3 energies attached (the ones you need to declare its attack), you can choose any attack from any dragon in your discard pile
Scramble Switch does the same thing, except you can also switch the Energy cards from the previous Active Pokmon to your new one, instantly giving it everything it needs to continue attacking seamlessly
