Palkia is #basic, which is a big advantage, but its energy hungry attack might be more trouble than its worth
[LLL] Thunder Flare 30+ Does 30 damage plus 10 damage times the number of damage counters on Lt
Easy to Clean & Long-Lasting
They don't copy whether that creature was tapped or untapped, whether it had any counters on it, whether it had any Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on
Finding only 2 out of 4 cards on the first go doesnt feel great, but the combination seems like it will be a cool fit if mana efficiency isnt your primary concern
