Your deck should utilize Hariyama (Mega Evolution 73) for its Heave-Ho Catcher ability, which allows you to drag an opponents benched Pokmon into the active spot when you play it to evolve your Makuhita
I like Overlord of the Mistmoors most because its in the primary blink color, it's a solid token generator in white, and the impending creatures are incredible if you can flicker them
A 7/7 Eldrazi for 7 mana with seven keyword abilities is nice, and Sire of Seven Deaths can be played in Eldrazi decks, or keyword soup decks
These effects can turn the tide in favor of the player or disrupt opponents, providing a path to victory
While certain other Pokmon, like Blastoise and Venusaur, carry decent value, none usually approach the level of Charizard
