Strategies
With
Rotobaga can be treated like a cheaper, but much weaker version of Threepeater, Tricorn, and Shooting Starfruit. However, it can dish out some big damage on turn 2, having the potential to do up to 4 damage at once if not blocked. Because it attacks on other lanes, you can use this to destroy a fragile zombie on its right before it gets to attack. It is especially useful against cards like Fire Rooster and Arm Wrestler, as you can avoid activating their abilities by playing this on an adjacent lane.
Because it is a root, you can boost its stats with Starch-Lord, although only Citron and Beta-Carrotina can do this normally. You can also use Navy Bean to boost its stats because of its Amphibious trait, but it is hard to keep Rotobaga alive until turn 4. However, Green Shadow's and Nightcap's boosting cards are more efficient if you want to boost Rotobaga alone.
But despite its uses, Rotobaga does have several weaknesses. The first weakness is its low health of 1, which makes Rotobaga fall from the weakest of zombies and tricks. Also, despite its Amphibious trait, playing it on an aquatic lane hinders its offensive power (assuming the aquatic lane is the rightmost lane), which is detrimental for a plant whose value mostly depends on it, although this does allow it to synergize with Bog of Enlightenment. But perhaps the biggest drawback of Rotobaga is the inability to defend its own lane, requiring support from other plants to do so. While it isn't a problem if the lane is empty, it definitely is in the case of the opposite. The most universal way to deal with this weakness is by using Bouncing cards such as Jumping Bean or Spring Bean.
Against
Because it is fragile, something that can do 1 damage like Conga Zombie or reduce stats like Nibble can easily take it out unless it has been boosted. Rolling Stone works too because of its low strength. If boosted, something like Rocket Science or Locust Swarm can destroy it.
You do not have to worry about it being on the aquatic lane, as your opponent will tend to not play it there due to it cutting down Rotobaga's power by half.
