Like most Pokmon cards, the value of Torchic depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Legendary Treasures)
These factors do still apply to modern Pokmon cards, just on a smaller scale (look up the price of an Umbreon VMAX, for example)
Id probably even go for a Dragon Shield Matte or Dual Matte instead of the Ultra Pro Eclipse, just because the taller sleeves might fill out the pockets a little better - though even then those pockets seem like theyll be pretty roomy vertically
Like all cards with tutor effects, Natural Order has only gotten more powerful with time, as the number of potential targets has increased
