Really, Tekuthals only downside is its mono-blue commander color identity
Ive spent hours researching public sales data from major auction houses, private market reports, and eBay sales to build one of the most comprehensive lists of high-value Pokmon cards in the hobby right now
For example: Pokemon ETB: Pokemon Center, Target, Walmart, GameStop, Amazon, Card Shop A Panini Prizm Hobby: Target, Walmart, Amazon, Steel City, Blowout Cards, Card Shop B MTG Collector Booster: Amazon, GameStop, Card Kingdom, Channel Fireball, Card Shop C Each row in your matrix is a product
these could include cards from any set from the beginning up through the current set
switch control of those monsters, and if you do, the monster you took control of becomes an Insect monster
