Sawtooth ThresherHow it works & interactions with other cards

Understanding Sunburst

Sawtooth Thresher features the Sunburst keyword, a static ability that functions as it enters the battlefield. When you cast it, the game checks how many colors of mana (White, Blue, Black, Red, and Green) were spent to pay its total cost. It enters with one +1/+1 counter for each unique color used. Because its mana cost is six generic mana, you can spend up to five different colors, meaning it can enter as anything from a 0/0 (if zero colors were spent via an effect) to a 5/5 creature.

Activating the Power Boost

The second ability of Sawtooth Thresher is an activated ability that costs 'Remove two +1/+1 counters from this creature'. This is a cost that must be paid immediately when you put the ability on the stack. In exchange, the Thresher gains +4/+4 until the end of the turn. Since this does not require tapping, you can activate it multiple times in a single turn as long as you have enough +1/+1 counters to pay the cost.

Strategic Timing and Common Mistakes

A common mistake is forgetting that Sawtooth Thresher will die if its toughness reaches zero. If it enters with only two counters and you remove both to activate its ability, it briefly becomes a 0/0 before the +4/+4 bonus resolves; however, state-based actions are checked after the cost is paid but before the ability resolves, which would cause it to be put into the graveyard. Always ensure the creature has enough counters or existing toughness to survive the cost payment.

Interaction examples

Sunburst vs. Fixed Costs

Meteor Golem

If you cast Meteor Golem, it always costs seven mana and has a set 3/3 stat line. In contrast, if you cast Sawtooth Thresher using two Forest, two Mountain, and two Plains, it enters with three +1/+1 counters because three colors were used. While Meteor Golem provides immediate utility by destroying a permanent, Sawtooth Thresher provides flexible sizing based on your mana base.

Scaling Power Levels

Psychosis Crawler

Unlike Psychosis Crawler, whose power and toughness fluctuate constantly based on your hand size, Sawtooth Thresher's size is determined by counters at entry. If you have five cards in hand, Psychosis Crawler is a 5/5. If you spent five colors to cast Sawtooth Thresher, it is also a 5/5. However, you can remove two counters from the Thresher to make it a 7/7 (3 counters + 4 power boost) for the turn, whereas the Crawler only grows if you draw more cards.
