Smeargle (Secret Wonders)
Smeargle is a good Pokemon, sometimes found in decks that gathers lots of energy.
What makes Smeargle good? The first attack, color pick. For no energy cost, you can search your deck for up to 3 basic energy cards. This is very useful for getting the energies.
Trace, Smeargle's second attack, is pretty good as well. For only 1 energy, you may flip a coin, if heads, choose one of your opponents benched Pokemon's attacks. This attack copies everything except the energy cost! So it's also good for after it's served it's original purpose (no names mentioned, Pachirisu). With 70 HP and only +10 weakness, Smeargle will defiantly have time to use trace. The joy of trace is that the biggest advantage your opponent can get if you leave the opener up too long is they can win by sniping. But with trace, that means Smeargle has a 50% chance of sniping back, if there isn't a better move available.
