pokemon aggron card - 67/111 - Crimson Invasion Colorless Artist Aggron - 80/124 - Cosmos

Black only just recently started getting Enchantment removal to the point that it hasn't really shown up on many spells yet, and all of them have been non-creature ones thus far outside of the tremendously overcosted Baleful Beholder and Ghastly Death Tyrant

A convincing reseal might not show every red flag, but its rare for a tampered product to show none of them

I would personally cut the Saheeli - you might not know this as a returning player but planeswalkers without any dedicated support aren't typically worth running in commander unless they have an immediate impact on the game (something like Ugin, the Spirit Dragon for example )

Aggressive decks can't afford to just slam their creatures into your 5/5, and even midrange decks usually don't have creatures that top 5 toughness
