IMO, Wizards are a much bigger threat than Octos. Octos are countered easily by M Grass, and I hear that Starfruit and Rotobagas work well too. Granted, those counters probably don't work in triple-digit Tiki Torch-er levels, but Wizards become unbeatable long before triple-digit Arthur's Challenge levels.
